• PowerCLI Script to migrate virtual machines with the same network Source for the new vCenter Server.

  Hi all

  I checked a few posts on the migration to the new vCenter Server virtual machine. But I'm not very good with Powercli and need some help here.

  We have a new vCenter server where we migrate virtual machines from one source vCenter server. Here are two things that I don't know how to connect together to make sure that bwfore we turn on the virtual machine to the virtual machine is connected to its source network.

  Part 1 - this script works well but do not get any network on the vCenter destination.

  cluster = Get-Cluster "clusterA.

  $inventory = get-Cluster $cluster | Get - VM | Add-Member - MemberType ScriptProperty-name "VMXPath" - value {$this.extensiondata.config.files.vmpathname}-Passthru-Force | Select-Object Name ResourcePool, folder, VMXPath |

  $inventory | Export-Csv c:\file.csv

  $inventory = import-csv c:\file.csv

  $cluster = get-group 'b '.

  {foreach ($vm to $inventory)

  $ESXHost = get-Cluster $cluster | Get-VMHost | Select - 1 first

  New-VM - VMFilePath $vm. VMXPath - VMHost $ESXHost - location $vm. Folder - ResourcePool (Get-Cluster $cluster |) Get-ResourcePool $vm. ResourcePool)

  }

  Part 2 - I want to preserve the Portgroup macaddress and the Ip of the virtual computers and connect them to the new vCenter. How can I do this with the script below. Or how can I combine them together?

  $vm_list = get-Cluster-name "clustera | Get - VM test * | Name sort

  $information = {foreach ($vm to $vm_list)

  $network_adapter_information = get-NetworkAdapter - VM $vm

  $vm | Select Name,PowerState,ResourcePool,@{N="Path; E=       {$_. ExtensionData.Summary.Config.VmPathName}},@{N="NetworkAdapter '; E = {[string]: join (":", ($network_adapter_information |))} %{$_. {{(Nom + "," + _.NetworkName $}))}}, @{N = "MacAddress"; E = {[string]: join (",", ($network_adapter_information | % {$_.}))} MacAddress}))}}

  }

  Step 2

  # Unsubscribe virtual machines

  Remove-VM - VM $vm_list-RunAsync Verbose - confirm: $false

  Step 3

  $cluster = get-group 'b '.

  {foreach ($vm to $inventory)

  $ESXHost = get-Cluster $cluster | Get-VMHost | Select - 1 first

  New-VM - VMFilePath $vm. VMXPath - VMHost $ESXHost - location $vm. Folder - ResourcePool (Get-Cluster $cluster |) Get-ResourcePool $vm. ResourcePool)

  }

  # Save virtual machines

  foreach ($info in $information)

  {

  $vmxpath = $info. Path

  $resource_pool = $info. ResourcePool.Name

  New-VM - ResourcePool (ResourcePool-Get-name $resource_pool) VMFilePath - $vmxpath - RunAsync-Verbose | Out-Null

  }

  Step 4

  # Put the network cards

  foreach ($info in $inventory)

  {

  foreach ($network_information in ($info.NetworkAdapter - split ":"))))

  {

  $virtual_machine = $info | %{$_. Name}

  $network_adapter = ($network_information-split ",") [0]

  $network_vlan = ($network_information-split ",") [1]

  Get-VM-name $virtual_machine | Get-NetworkAdapter-name $network_adapter | Together-NetworkAdapter - NetworkName $network_vlan-Verbose-RunAsync-confirm: $false | Out-Null

  }

  }

  # Start the virtual machines

  foreach ($vm to $vm_list)

  {

  Start-VM - VM $vm. Name-RunAsync Verbose - confirm: $false | Out-Null}

  }

  Thanks in advance for any help.

• vShield Migration to new vCenter

  Hello

  I'm planning an upgrade of our environment vSphere vSphere 5 6 by building a new architecture of vCenter/PSC and then migrate VM guests on the new vCenters.

  We use 5.1.2 POSSIBLE which I plan to migrate to POSSIBLE 5.5.4 and migrate to the new environment.

  POSSIBLE, we have a vShield Manager and 12 vShield edge devices that handle isolated bubble environments with a lot of firewall and NAT rules on each.

  I tested the process and migration, including the upgrade to 5.5.4 and migration POSSIBLE vShield Manager to the new vCenter and all works well.

  Migrated vShield edge devices work perfectly and their firewall rules all continue to work properly.

  The problem is that when you go in vShield Manager there now new data centers listed, and if you click New data centers there is no configuration in any of them.

  This means that I can not change the configuration of the any of the vShield edges so they are stuck with their set of existing rules.

  To test, I recorded the vShield Manager to return to the original vCenter and the old data center, I see all the edges to configure, but of course it cannot update the settings on them because physical devices no longer exist in this environment.

  The question is, is it possible to move the configuration that vShield Manager knows that there are in the new data center and manage all the edges that have been migrated?

  For example, is it possible to change the Manager vShield configuration database and the datacenter somehow references so the configuration is less visible from the new vCenter.

  I'm really not looking forward to having to recreate all these edges as there are currently a lot of rules in these...

  We have completed our upgrade and migration now and used a combination of processes.

  Below is essentially the whole of the process used.

  (1) upgraded existing vShield Manager and edge v5.5.4 (no effect on the edges running)

  (2) built a new U2 vCenter 6.0 environment

  (3) built a new vShield Manager server connected to the new vCenter

  (4) manually recreated new edges on the new vShield Manager

  -All our sides have basically the same rules so that we all firewalls and NAT configured on an edge rules and then transferred these rules to the remaining edges using the Rest API

  (5) to migrate all 5.0/5.1 for the new vCenter ESXi hosts

  -At this point, all the edges on the old vShield Manager continued to operate fully but could not be reconfigured because their configuration has been stored in the old vCenter.

  (6) upgraded or rebuilt all ESXi hosts to 6.0

  (7) to stop the old edges when it is able to plan outages and deployed a new benefit of the new vShield Manager to replace

  -At this point, we now have a fully managed, deployed and operational edge device that can be configured.

  I made a service call to try to get access to the database of the Manager of vShield directly, but they would not give me the credentials to use

• New Vcenter server and host add

  Hello, we are planning to create a new server Vcenter.  Had a bunch of weird issues with Vcenter.  Vcenter 5.1 on Windows running.  have not decided if we will use the VCenter, or create a new virtual machine from Windows to Vcenter again but I don't think that will count for my question.

  My plan is to turn off HA and DRS on the old server Vcenter, then remove a host from the old server Vcenter, and then add this host on the new Vcenter server.  Then just repeat the process for each host.

  My question is, should I turn off any virtual machine running on the hosts before removing the old server vcenter?

  If I remember correctly you have not, the virtual machine must remain in place and running, no connectivity should be lost and users should not not the difference.  We plan to do this off-peak hours, but there are always a couple of vm that are used 24/7.  It would be therefore rather not have to stop first.

  Thank you

  Hi defrogger

  Yes, it's the right way to migrate a new vCenter ESX Server.

  Disable HA/DRS and then disconnect the ESXi, vCenter server and plug them into the new vCenter.

  By disabling the DRS, you will lose the Resource Pools. So its maybe you assign only manual DRS.

  Another thing that many people forget are the options of the virtual machine on the cluster options. they have been set up again on the new cluster.

  BTW. There is a guide of vmware:

• Migration to new vCenter

  I have two vCenters up and running, ESXi 5.0 and 5.5 of ESXi. Our existing environment is 5.0 and 5.5 is a new environment, I built (we decided to not upgrade the environment existing for various reasons).  I'm trying to figure how best to migrate all our VM (over 100) of 5.0 to 5.5 quickly and with the least amount of downtime and I was wondering what others have done in the past.  We have different loads of work on those virtual machines (IIS, SQL, file servers, etc.) and I am open to any suggestions/ideas.

  Thank you in advance!

  Hello

  According to the Matrices of the interoperability of products VMware ESX/ESXi 5.0 is compatible with vCenter 5.5, you can add the 5.0 hosts to vCenter 5.5.

  Enter the vSphere 5.0 5.5 vCenter's existing licenses.

  The shared storage is accessible by two 5.0 host and new 5.5 hosts?

  If Yes, then you can vMotion 5.0 host to new 5.5 hosts so that they have the same series CPU, the procedures are described here: Library of vSphere 5.5 - movement of Virtual Machines using vMotion during an upgrade

  This allows to check the CPU/matrix series: http://www.vmware.com/resources/compatibility/search.php?deviceCategory=cpu

  If they belong to different series of CPU, you can perform the Migration cold (requires downtime) Library of vSphere 5.5 - Migration of virtual machines

  Cold migration: moving a VM power off to a new host. Optionally, you can move the configuration and disk files to new storage locations. Cold migration can be used to migrate virtual machines from one data center to another.

  
  

  If you are using a shared storage, even, you can also perform migrations as below:

  1. turn off the VMs system in the old 5.0 hosts

  2. Remove VMS in vCenter inventory 5.0 (note the location of the files in the data store) library of vSphere 5.5 - remove virtual host computers

  3. Add VMS to vCenter inventory 5.5 5.5 Documentation Center - VSphere to return a virtual machine or the template to a host

  4. turn on the VMs and check.
  

  
  

  If the shared on 5.0 storage is not accessible from 5.5, you can perform LUN or migration cold.

  LUN migration requires less compare to cold migration downtime.

  LUN Migration:

  1. present the storage shared existing 5.5 guests.

  2. after the 5.5 can access the existing shared storage, stop the virtual machines

  3. remove virtual machines from existing inventory of the vCenter 5.0

  4. Add VMS in vCenter stock 5.5
  

  5. turn on the VMs and check

  6 storage vMotion the VMs to new shared storage (you can also perform Storage vMotion first, but you will need to present the new storage shared for guests 5.0)

  Cold migration:

  1. present the storage shared existing 5.5 guests.

  2. after the 5.5 can access the existing shared storage, stop the virtual machines (for consistency of data)

  3 clone virtual machines from 5.0 to 5.5 new hosts guests (you can rename the old VM so if you want cloned the new VM will have the name of the old virtual machine)

  4. make sure that the old VMs are turned off

  5. turn on new new 5.5 host virtual machines and check

  6. remove the old virtual machines in inventory, or remove disks

  7. If you need to rename the virtual machine name, rename the virtual machines and run Storage vMotion to different data store VMware KB: rename a virtual machine and VMware ESXi and ESX records

  You can try to migrate 1 VM first, or simply create a new dummy virtual machine and choose 1 5.0 ESXi host to test migration.

• PowerCLI script to migrate virtual machines to the new vCenter environment

  Hello world

  in the next few weeks, we need about migrate 700 VMs (Windows/Linux) server to a new environment (new vCenter, new hosts, but VMs will remain on same data warehouses). VMs will be migrated not in one batch, but rather from time to time (which, however, can understand the need to migrate some 10s of virtual machines at the same time).

  Cluster names and folder structure will be identical to the old and the new vCenters. As host in the new vCenter names differ from those in the old vCenter, thought to provide a table of 'translation', which tells the script to save a given VM on host B (new vCenter) when having been registered in order to host a (old vCenter) and so on.

  I thought writing a PowerCLI script which, broadly speaking, can accomplish the following steps:

  • Connect to vCenterOld and vCenterNew
  • Correspondence table of host to read from a file (see step "register VM vCenterNew below)

  Then, in a loop:

  • Ask VM name
  • Get the settings of the virtual machine: Datastore/path, network/Portgroup, HA restart priority, host, folder, note
  • View the parameters and the VM name and request confirmation migrate the virtual machine
  • Turn off VM (closed OS gracefully, but force power off if power status is still not equal 'off' after a time given)
  • To unsubscribe from VM vCenterOld (removal of inventory)
  • Registry of the VM to the data store vCenterNew (assumptions: same folder as vCenterOld, host names are different, but for each source in vCenterOld host a host of destination in vCenterNew for you join the virtual machine to can be provided, that is, CSV)
  • The value of VM portgroup (same name as in vCenterOld)
  • Set VM HA restart priority
  • PowerON VM
  • Wait / check the VM (for example, ping) connectivity / continue immediately if the virtual machine is accessible or after a certain time if the virtual machine is still inaccessible
  • Confirm that the virtual machine has been migrated successfully, OR ask the user to check the connectivity of the virtual machine

  Now to my questions:

  • Is anyone know about an existing script that does something similar or contains parts that can be useful to compile a script like this?
  • How can vCenter two connections at the same time been managed within a PowerCLI script - or doesn't work at all and a connect/disconnect to/from the two vCenters must be completed for each virtual computer?

  Many thanks for any help.

  The following seems to work for me

  $vm = Get-VM -Name MyVM$nic = Get-NetworkAdapter -VM $vm $vdPG = $nic | select -ExpandProperty NetworkName
  
  Get-VDPortgroup -Name $vdPG
  

• Moving hosts to new vCenter and retaining current licences for guests

  I need to upgrade an environment vSphere 4.1 to 5.1u1. I plan to install a clean vCenter 5.1 and need to migrate hosts without interruption to the virtual machines. The way to remove the old vCenter may not be because it requires the host mode maintenance and VMs to be evacuated. What plan do is disconnect from the host and have the new vCenter appropriated. I will then possibly incoming days guests through VUM to 5.1u1.

  My question is when the new vCenter appropriates the hosts what will happen to the licensing of 4.1 esx/esxi hosts? Will be the current 4.1 esx/esxi licenses follow the hosts or will I have to add the esx/esxi through the client license? The new vCenter will be installed in trial mode until licenses can be provided for me.

  A second question is when the esxi hosts are upgrading to 5.1 and I did not upgrade licenses will guests enter a grace period until a license can be applied? I don't know how long the hosts were in trial mode, before 4.1 licenses applied so I assume every 60 days were used.

  With adding hosts to the new vCenter Server, the license key from the host server will be added to the repository of the vCenter Server license; Even if this is not the case you could simply add the current license key to the new vCenter Server manually. Just make sure that you do not use more CPU that purchased licenses.

  Once you upgrade the host, make sure you have the new license keys already available. As much as I know there is no evaluation period additional to the hosts upgraded who were running older versions of 60 days. The grace period of 14 days you mentioned applied to versions in ESX 3.x used FlexLM licenses (i.e. license files).

• Migrate VMS in vCenter former 3.5 to new vCenter 5.1

  I had (no license maintenance) situation where I have not maintained old environment VMWare vcenter and esx servers running in version 3.5. SAN is mixed two IBM N3300 iSCSI/NFS. All this will be removed from use. Then I got new brilliant vCenter 5.1 environment (new licences), is EMC e iSCSI SAN.

  I was wondering if I could really get the old N3300 on new vcenter, start the computer virtual and storage vmotion them away? But how VMWare reacts if the storage is mounted on two different groups? I should probably remove old vcenter storage before going up again?

  Hosts sharing the same LUN do not need to be in the same cluster, or even in the same environment - I'd go ahed and add logic unit number to the new environment to ensure that you are able to see the storage as well as the files that make up the VM - the steps that I follow are:

  1. Turn off the virtual machine
  2. Reove the VI3 environment (right click on the virtual computer name and select Remove from inventory)
  3. In the new environment, navigate to the location of the VM configuration file (.) VMX) on the LUN and add it to the inventory
  4. Turn on the virtual machine

  You can delete the original ESX host storage and adds it to the new environment - virtual machines should be discontinued for as long you need to add the storage to the new environment and the machine virtual to the new environment, but I think that the above method will be less intrusive and provide a more reliable migration

• Migration 4 and 3.5 ESX hosts again vCenter Server 4.0

  I'll put up a new vCenter Server 4.0 with an Oracle database to take the place of two vCenter using express databases included. They are both on the hosts recommended 5-50 VM for the Express database, oops.

  The first is vCenter 4.0 which uses the express database included is on a Dell 1950 server. ESX 4.0 hosts are on 2 groups on Dell blade servers that have 5 blades per cluster and are using storage arrays EqualLogic iSCSI for data warehouses. More there are a few individual Dell R900 and Dell R710 servers use local storage connected to the vCenter.

  The second is vCenter 2.5 that uses the express database included running on a Dell 2950 server with, like 20 other Dell running ESX 3.5 of 2950 using local storage.

  Looking for a vision a little and advise the host migration to the new server vCenter Server.

  Thank you... Jim Hurley

  I would say the easiest would be to create new vCenter new host OS (I would choose 64 bits that will put you in the conditions required for 4.1).  Once the new vCenter Server online, I then install a standalone license server for your VI3 hosts, then begin to disconnect and remove other environments and new hosts.

  Stand alone license server can be found

• Create new vCenter and move the ESXi hosts

  Hello

  I created a new vCenter vCenter apparatus using ISO 6.

  The deployment went well and I have all the installation program. I would now like to move hosts our old vCenter to new ESXi.

  I was reading this article to start the moving process.

  When I try to disconnect the host I get the message below

  

  In the article in the link above it is written that it will not affect the State of the virtual machine running on the host.

  If I click on 'Yes' here, it will automatically put the host in maintenance mode?

  I prefer not to do it if I can avoid it because I don't want to have to evacuate all virtual machines running on the esxi host.

  Wouldn't it be better if I disabled it HA first? Then try to move hosts? Or I'm sure to sign-out and the subsequent removal?

  Thank you

  See you soon

  Hello

  You must put your server in maintenance as a first step mode, then unplug and remove the server. It will work.

  If it doesn't work, disable temporary HA and remove your host of the VC.

• 5.1 ESXi host rest disconnected when it is connected to the new vCenter Server 6

  Hello

  I created a new version of vCenter Server 6.

  I have e vCenter Server 5.1 connect my 5.1 hosts.

  I want to connect hosts to the new vCenter and then upgrade to ESXi 6 guests.

  I disconnect hosts on the old vCenter.

  The I connect hosts to the new vCenter, and it happens with all the vm´s, etc..

  But it is disconnected.

  And it keeps beeing disconnected even when you try to connect again.

  If anyone has experienced this?

  Thank you

  Thomas

  Have you added these hosts in your new server vCenter along with their licenses?

  Otherwise, if please add host license in your vCenter license inventory and assign to those of your hosts and then try to re - connect.

• The steps required to perform a migration to a new server vCenter using distributed switches?

  We are currently on version 5.1 of vCenter and ESXi 5.1 on all our guests.  We use a vDS on our current server vCenter and will need to migrate to a new server vCenter soon.  Is there a documentation about the steps to migrate to a new server vCenter using switches distributed?  We hope to achieve this goal without any downtime.  The problem is that we need that VDS on our 10GB network for the aggregation of links.  If having to migrate guests at standard switches before moving them to the new vCenter server, there will be problems of network performance.

  Because information about your environment are stored in the database of vcenter al you should just be able to stand up the new vCenter server and that it points to the existing database

• Migrate to ESXi 4.1 hosts to VCenter again

  Hey volks!

  Today, I finished with the installation of a new server VCenter 5. There is another VCenter 4 Installation that actually manages our ESXi 4.1 hosts. Now I would like to move the hosts to VCenter 4.1 environment to the new (5) a.

  Is there a way without having to move the hosts in Maintenance Mode?

  What I read on the web - can I just uninstall the agent, but no guide step by step has been found and I would prevent mistakes when doing. Also, I think that this is not a good way to do it, or?

  I'm sure someone did it in the past and can enlighten us on this.

  Thanks in advance,

  Matthias

  NAAA it should be simple. Cluster resources can be a problem, but I don't see it as a big deal,

  1. Disconnect host VC4
  2. Remove the host of VC4
  3. Add a host to VC5
  4. and repeat step 1-3 for all remaining army.

  vCenter and HA agent will be installed automatically when add you the host to the VC5
