Query - moving from ESX 4.0 (cluster) to ESXi 4.1 (cluster) license

Hi all

Am very new to VMware, please bear with me.

We have in our existing Production cluster, consisting of three (3) 4.0 ESX servers and the intention is to replace them with ESXi 4.1 (U1) (under license).

The plan should gradually slide each ESX 4.0 Server and install ESXi 4.1 (U1) of an image from HP directly on top.

No drama it (?), but what about the licenses...

I have a few questions I have to date not been able to acqurie myself.

  1. With each of the VH in the Production cluster, are we able to move a server in the cluster, upgrade to ESXi 4.1 and go back to the same cluster?

  2. If NO to question 1, which would be the recommended upgrade path where there is one (1) cluster, three VH (currently ESX 4.0) and we replace with ESXi 4.1 (U1).

    We have x 1 vCenter Server Foundation 4 license and three(x3) vShpere4 licenses advanced.

    Must these licenses be updated too?

Am deparate to find answers to these questions.

Kind regards

Cameron

HI - welcome to the community.

The answer to your question is YES - you can re - allocate your ESX 4.0 license to your hosts updated. the license is generic and can be removed from a host and added to the other using the License Manager.

  • Moving from ESX 2.5.3 / TC 1.4 to ESX 3.5 / VC 2.5

    I have been instructed to upgrade an older 2.x/VC ESX ESX 3.5, VC 2.5 1.4 environment.

    The old VC with SQL 2000 Server local server will be used as the new server VC 2.5, but I'll pass the DB to another server SQL with SQL 2005. We have a San for the old that ESX Servers I will use for the new environment.

    This is my plan:

    1 upgrade the old VC 1.4.1 server for VC 2.5 (including the upgrade of the DB).

    2. move the DB in the local SQL 2000 to SQL 2005.

    3. install a new ESX 3.5 server.

    4. Add the new ESX 3.5 server to VC.

    5. use VMotion to migrate the virtual machine of the old servers ESX 2.5 to the new server, ESX 3.5 (on a new VMFS datastore).

    6. turn to level hardware VM VM2 to VM3.

    7. Upgrade VMWare tools on all virtual machines.

    This sounds like a plan accepted for migration?

    Okay, Yes, it's very close.  I would upgrade DB (SQL 2005) first of all, given that the NEW Victoria Cross, it will take a new scheme and I think you will find that its best start over with a NEW VC.  It's a lot of changes, and I'm not sure that VC can evolve easily, sounds good in theory, but I wouldn't trust him.

    So once you have the new Victoria Cross, you can migrate your virtual machine, because you can add 2.5 machines to a VC 2.5 server, thus putting under one roof all the VM.  Then you roll off the ESX host, upgrade to 3.5, then migrate back to the virtual computer.

    I also wouldn't upgrade ESX 2.5 to 3.5 which has many problems.  You migrate VM, remove ESX 2.5 cluster, blow ESX 2.5, reinstall ESX 3.5 as new.  Then add the new ESX 3.5 to the cluster.  Migrate the back of the virtual computer.

  • Moving from ESX 3.5 to ESX 4

    If I have a server ESX 3.5 hosting windows 2003 32-bit servers, is it possible to use something like vRanger connection or Veeam to move this 32-bit server on a host ESX 4 64 and some run as if they were on it original host? Trying to set up redundant servers, I felt I could move my 32 on the 64 - but certainly not the other way around. Also if it is a temproary thing (as I'm waiting for the 32-bit hardware redress), move them back without problem?

    I just suggested that If had shared you storage that you could just add...

    I don't know how many virtual machines total you have or their object, but I would say that 2 new servers with enough RAM could accommodate a large number of virtual guests. Eliminate the 32-bit devices or use the 32-bit hardware to create a shared storage.

  • Do we not have to change the settings for the virtual machine once moved from 2.5 ESX to vSphere 4.1?

    Hi guys,.

    I just wanted to check, once the virtual machines are migrated from ESX 2.5, 2.5 Vcenter to ESX 4.1, Vcenter 4.1 of the NFS datastore on the iSCSI data store.

    Do I have to make changes to the vm settings?

    To use the features to enhance available with ESX 4.1 what I need to change the virtual disk to logical Bus to LSI logic? What is recommended or is not serious?

    It will be very useful for me to know if there is any need for changes to be made other than on the virtual machine upgrade vmware tools.

    Thank you

    You try to run ESX 2.5 VM on ESX4.1, if that's the case then ESX 2.5 VM are not supported on ESX 4.1

  • I'm moving from PC to iMac. I think that I have brought successfully my profile. My work id of addressbook, but no mail received file is obvious.

    I'm moving from PC to iMac. I think that I have brought successfully my profile. My work id of addressbook, but no mail received file is obvious. The Mail subfolder in the profile of 'new' - "Mail" - is about the same size - 1.6 GB - as it was on the PC, so I guess that the mail has not moved, however, there is no sign of what I can find on the page "news" of Thunderbird. I did move by copying the profile folder of the PC on the Mac desktop, raise the profile of Mac beside him folder and dragging the PC Mail subfolder to the mail folder in the Mac profile. I think I am way over my head here; I really want to solve the problem, so I can mothball the PC. Thanks is advance for your help.

    OK, the ini file will be

    MacHD>Users>RKW (me)>Library>Thunderbird
    

    The profile folder will be in MacHD > users > RKW (me) > library > Thunderbird > profiles with a name like d1234pg. By default. When copying content. It is this lower level folder called. Not MacHD > users > RKW (me) > library > Thunderbird > profiles.

    To simplify a little (I hope so.

    Install Thunderbird. go to the Help menu in Thunderbird and select troubleshooting information.
    In this tab, click on the button show the frlder for the profile.
    Finder will open with the open current profile folder.
    Close Thunderbird.

    Now, locate the old profile folder, it will be contains pref.js as a file among many others.
    Copy the files and folder to this folder, and place them in the new folder Thunderbird open in the Finder for you. To replace the files.

    Open Thunderbird and you should have it all.

    "You can connect to the server through a proxy server" what is a proxy server address

    Hi @Raggetty ,

    I understand that you are having problems with the printer via the wireless network. I will definitely do my best to help you.

    Since you have moved, you must install the printer on the network.

    If you haven't already done so, restore the default settings of the network printer. Go to configuration, network, restore default network.

    Then set up the printer on the network again.

    Follow this document:

    If you need help to set up the printer on the network, let me know.

  • Messages do not automatically moved from the Outbox to the sent items

    Hello. Everything worked fine until 08:00 this morning.

    Now, when I send an email, it is sent but is not automatically moved from Outbox sent items. So, I get an error message (but no error code. He says only: "some errors occurred while processing the requested tasks"). Because the message remains in the Outbox if there is another message to send that it will send the first once again, and then the second, then the first again, then the second again, etc. The only way I can work around it must manually move each e-mail sent from the Outbox to sent items. The messages are efinitely goes recipients because they are responding to their

    You have apparent dbx file corruption.
     
    Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.
     
    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.
     
    In Windows XP, the files of user OE (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.
     
    With OE closed, find the DBX files for the items in the Outbox and sent and delete them.  New ones will be created automatically when you open OE.
     
    After you're done, followed by compacting your folders manually while working * off * and do it often.
     
    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.
     
    General precautions for Outlook Express:
     
    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

    Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the CPUs, slows down sending and receiving and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for the loss of messages. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:
