Upgrade or ReBuild vCenter

Good afternoon all,

I am preparing some major changes to my new company VMware environment.  We currently have approximately 12 hosts running between ESXi 4.0 and 5.1 ESXi and each generation in-between.  vCenter is obviously 5.1, and he runs the local SQL Express DB, always running at 4.6 GB (I know 5 guests and 4 GB are the limits).  So my question is, knowing I have to do an upgrade to vCenter for 5.5 can I upgrade the server and move the database, or to build a new virtual machine from scratch and install vCenter 5.5 fresh with a new database.  The vCenter server seems to have been initially installed as 5.0 and upgraded to 5.1, so it would be the second upgrade made to it.  During my rebuild of the environment I will wipe/rebuild all hosts and demolish, rebuild all clusters in the environment and rebuild all storage.  I'm leaning towards a complete reconstruction, given that much else happens, but wanted to bounce the idea of others.  Let me know your opinion.

Thank you

John

Since you will be demolish and rebuild your vCenter (horns down clusters and reconstruction) environment, I'd build a new vCenter-

    I did some digging in the vmvcsr.log file and noticed that it changed the SetupDir and the SETUPEXEDIR to Z:\vCenter-Server instead of Z:\vCenter-Server\

    I added the SETUPEXEDIR = and SetupSource = command line options and the installer still changed their return. "So, I removed the v'" and put the directories all in escaped quotes. This solves the problem.

    I still think that the installer must put the correct path on its own source dir facility. It should be smart enough for that!

    Here's the line Arguments that worked:

    $processInfo.arguments = "/S /qr SourceDir=`"$sourceDir`" SETUPEXEDIR=`"$sourceDir`" DB_EXISTING_VERSION=550 DB_USERNAME=`"$AdminUser`" DB_PASSWORD=`"$AdminPass`" LAUNCHWIZARD=1 VCS_DB_BACKUP=1 SSO_ADMIN_USER=`"$AdminUser`" SSO_ADMIN_PASSWORD=`"$AdminPass`" /L*v $env:temp\vmvcsvr.log"

  • Upgrade memory of VCenter Server

    Hello

    Can anyone tell how to change the memory in my server vcenter?

    It has already been upgraded to version 10 and the use of the customer is no longer an option.

    Welcome to the community,

    This is probably the main reasons for the warning in the documentation anyway, there are two ways to change the settings of the vCenter Server VM. If you have 10 of VMware Workstation in place, you can connect to the host on which is inscribed the vCenter Server VM and manage settings, another way is to use a PowerCLI script to do this. Last but not least, you can simply change the VM manually .vmx file through the CLI (console or SSH). In this case, remember to reboot the virtual machine after editing the file .vmx (see http://kb.vmware.com/kb/1026043). In all cases you must stop the server vCenter Server to change the settings. This can be done by connecting directly to the appropriate of ESXi host using the vSphere Client.

  • Upgrade paths for vCenter Server 4.0/32-bit to 64-bit/5.0

    So, for various reasons beyond my control, when we installed vCenter server when we migrated from 3.5 to 4.0, it has been installed on 32-bit Windows.

    Data backended by a full instance of SQL Server (not the MSDE version that comes pre-packaged with vCenter).

    So, I try to understand the strategy of less impact for the trip to 5.0.

    One idea I had is simply to build a new 'home' for vCenter Server on x 86-64 and point the application on the existing database running on 32-bit windows server. (I'm guessing that the 32/64-bit nature of the database server itself is largely irrelevant as it allows 64-bit vCenter Server to talk to it). I think then that all information cluster all would remain intact since it's in the database, etc..

    If I had to, I guess, we could install vCenter 4.0 (64-bit) on the new host and THEN perform the upgrade, if it was really important, but I somehow don't think it is.

    Once that is done, we would eventually just make a backup/restore type upgrade path to move data out of the old host and the new host and re-point vCenter Server in its local database now.

    A that someone does something similar to this? Traps, we should be aware of? Warnings that it would never work the way we expect it to be, etc, etc. ?

    That's what I'd do.  It your DB is remote, it is a fairly straightforward upgrade.

    1. turn off your old Instance vCenter

    2. backup your DB instance

    3 copy the SSL directory off the old vCenter and the new (you'll probably to manually create the path, before installing vCenter)

    4 set up your ODBC connection and test

    5. install vCenter and use existing DB

    Assuming that you are going to use the same host name and IP address for your new instance of vCenter, like your old, all stocks will be as it was before the upgrade.

  • Move and upgrade the server vCenter Server

    I'm about to move our vCenter server and our database out of our ESX cluster. The current server is version 4.0.0 using a database server SQL 2008 32-bit (on a separate server).

    I created two new 64-bit servers in 2008, one for vCenter and one for the SQL 2008 64 bit server. Ideally, I would like to move my database from the old SQL Server to the new, installing vCenter 4.1 on the new server and simply point to the migrated database.

    My question is, will this work as expected or that I can't point vCenter 4.1 to a database that has been used with vCenter 4.0 because the structure of the db is different? Basically what I need to install vCenter 4.0, that it points to the migrated database and then upgrade to vCenter 4.1? Thank you.


    Dan

    Hello Dan,.

    VCenter Setup will recognize the old DB scheme and modernize the DB accordingly.

    You can 'new' installation vCenter and point the installer to the DB migrated using an ODBC connector and the installer will run the scripts to upgrade DB on the DB.

    As suggested before, make sure you have a full backup of the DB in which case you would need to return to the upgrade.

    See you soon!

  • The upgrade of the VCenter 2.5.2 update 4 vCenter 4.0

    I am preparing to update our virtual Center Server.  I read in the guide.  It seems straight forward.  I have listed the steps that I follow. Any comments or advice would be appreciated.

    1. our Oracle database and resides on another server.  The DBA will upgrade the 11g database before the upgrade to vCenter.  This was recommended in the guide

    2 upgrade vCenter Server - our virtual Center Server is a physical box.  We currently have loaded on the Server Update Manager, converter, and Capacity Planner.  I watched the video of upgrade and it suggested to have these additional software loaded on another server.  Is this a good practice?  Does anyone have these load on their virtual Center Server?

    3 HA\DRS - I have three HA\DRS clusters.  Problems with this reconfiguration after the upgrade?

    4. I manage 3.0.1 by 3.5 hosts with the new version of vCenter.  Fix ESX, one host at a time in the coming months.  Expected problems?

    Thanks for any help!

    Don't believe the hype.  What's weird, people have no problem to put 4 vCPU virtual machine and 16GB of RAM and SQL server, but on a PHYSICAL machine, they wince over 2 services on the same machine... I find it VERY strange.

    We UM, Capacity planner, blah blah converter on the same machine, no problem.  They are on one different server other than VC however, only because at the point where I was trying to diagnose a problem with the Windows machine, and it turned to be a driver for the CARD, which has long since been corrected.  When I updated to 4.0 VC, so these are all on the same box... Well good except for the UNIFIED messaging and it is only because the other machine has back-end storage / DB that I want to use instead, but this isn't a problem.

    > 4. You will manage 3.0.1 by 3.5 hosts with the new version of vCenter. Fix ESX, one host at a time in the coming months. Expected problems?

  • Upgrade a undersized vCenter Server

    A vCenter server for a small farm (4 hosts and about 200 VM) has been installed originally on the undersized material and should now be moved to an appropriate host more.

    I see two options, implementation of a crowd to dedicate or a virtual appliance.

    • If I select a dedicated physical host and perform the procedure on the page http://kb.vmware.com/kb/5850444, RAM-how much should I be implemented, given the same host must act as vCente and Update Manager? Based on the documentation, I'd than 4 GB, but from my experience I'm not sute 4 GB are enough: can someone please suggest good memory sizing?
    • If I select a virtual appliance, can I migrate the vCenter cuttent leave the host physical currend to the virtual appliance?
      • Given I can migrate the current vCenter to a virtual appliance, what are the disadvantages of the implementation of a virtual appliance instead of a physical host?

    • As can a last chance, I use VMware converter to convert the current vCenter to a virtual machine and install it inside the vSphere infrastructure?

    Concerning

    Marius

    The steps you mentioned should work ok. After the conversion of the virtual machine, make sure you reconfigure the IP settings and remove any material about the drivers and services that have been installed for the physical host and then install VMware Tools. I still suggest stop you the vCenter Server services and SQL-Server (in the case of a local installation) on the physical host computer before you start the conversion.

    About HA, vCenter is required for HA configuration. HA itself independently on the hosts, vcenter Server. While the vCenter Server is turned off the VMs system will continue to operate and some features such as vMotion, DRS,... which are initiated by vCenter Server is not available.

    I guess you don't have any other feature as View Composer,... installed on the server vCenter Server!

    I am trying to upgrade our server vCenter version 5.5 to 6.0, but this is a boxing match, and so far the vCenter Server won I'm afraid...

    The problem is that I get an error when you install saying: "unable to install the servie collector syslog", and list a few files, then an error saying "Installtion of the component VCSServiceManager failed with error 1603" code.

    Our implementation: Windows server 2008 R2, all services of vcenter, including sql is on the same server. Only a vcenter server as well.

    I have read a lot about this kind of problem and tested a few things, but have not yet found any solution.

    • The time is the same on the vcenter server as on the rest of the field.
    • Windows install the value automatic and started
    • The ODBC can communicate with sql and leak white spaceat the end of the name
    • An IPv4 address is set and no IP address conflict.
    • The user to make the upgrade a sysadmin on the database.
    • Tryied with a fully patched Server

  • vCenter upgrade from 5.0 to 5.5 for the new machine, SRM and dvswitch

    Anyone know if it is possible to do a upgrade to vCenter from a machine under windows server 2008 on a new computer server 2012? The database is located on an external computer. All I can see in the upgrade doc is that there is a tool for migrating data with earlier versions, but not when moving to 5.5.

    Also - what implications are there if there's a dvswitch in the site?

    Thank you very much

    Hello

    I guess you run ESXi and vCenter 5.1?

    If it were me, I'd do the following:

    -Install a new instance of vCenter on a new Server R2 2012

    -Turn off the old server vCenter on 2008.

    -Save the remote SQL database vCenter.

    -Install a new instance of the Web, the inventory Service and SSO client. I remind vCenter to use the SQL remote database existing and chose to 'upgrade' when installing vCenter.

    Then you'd be in vCenter server 2012 R2 with a new facility and using your old database that will get upgraded. You will always retain so your dvSwitch information. I'm not sure of SRM, you probably need to reconfigure it to use the new vCenter Server (unless you use IP records or that you can easily return?).

    There are a few things to think about when you really do. Can you afford any downtime on vCenter? What of SRM and your RPO/RTO? The complexity is your configuration of SSO? Use you things like tags in web client (they would get lost in the reconstruction of the inventory service)? What confidence you are on the side of things RS? It is possible to save these configurations, but I'm not sure restore them on 5.5.

    The main thing to consider is the database really. Worst case, you can restore it and turn back on your old vCenter 2008.

    Happy to be told I'm wrong or answer your questions. If in doubt, contact VMware technical support and ask for help.

    Kind regards

  • Upgrade to vCenter 5.0 to 5.5 - agent backward compatibility?

    I'm moving from 5.0 to 5.5.  As I did this is that I have a VM vCenter standalone.  I cloned it (run sysprep, etc.) and then upgraded the clone to not touch anything we have in production.

    When asked to upgrade the agents on the hosts, I chose that I have them will modernize manually at a later date.

    So first of all the question, are backward compatible with 5.0 agents?  Or once that I upgrade, only vCenter 5.5 will be able to connect?

    What is the best way to return to agent 5.0 if I have problems after upgrading to 5.5 agent?

    In my client web vCenter 5.5, I'll try to add the hosts when even just to see if there is a connectivity (understand an error message could say that much) but I don't see a way to add them manually.  It appears when I select hosts, he starts searching for them (and can't find anything that is what I expected).

    I want to just make sure that what seems to behave correctly because there is no agent 5.5 host out there.

    Thank you much for the help.

    vCenter Server 5.5 supports the hosts of version 4.x and later... There is no need restoration agent and you can still run the vCenter Agent pre-upgrade Checker host before upgrading the server vCenter Server.
