In-place upgrade from Hyper-V 2008 Server to Hyper-V 2008 R2 Server? RRS feed

  • Question

  • Searched and haven't found any concrete documents regarding this so....

    I have a Hyper-V server (Host) virtualizing a Sever 2008 SP2 machine (guest).  Is an in-place upgrade from Hyper-V server to Hyper-V server R2 possible?  Any steps that I would need to follow?  How much down time should I expect?

    Many thanks.

  • Sorry about the late reply.  I've spent 2 weeks figuring out why the server wouldn't boot from the usb flash that I used to install Hyper-v 2008 R2 server, just to find out that I got a corrupted ISO download.......

    So, in short, yes, it seems to work.  My hyper-V server was joined to the domain and after the upgrade, everything seems to be solid.  I wonder why this wasn't a supported upgrade path.....

    Steps:

    1)  Optional:  Perform individual backups within the VMs.  Call me paranoid but VMs are just like physical machines.  Better safe than sorry....
    2)  SHUTDOWN all VMs.  I would disable auto-start on VMs as well.  Again, just to be safe.
    3)  Backup the Hyper-V Server with WSB, including all VMs.  Upgrading is a high risk task.  Better have as many contingency plans as possible.
    4)  Export all VMs to external/attached storage.  If in-place upgrade fails, I can always perform a clean setup of Hyper-V 2008 R2 server and re-import the VMs.
    5)  Insert HV2008R2 server DVD into the machine (I used a USB flash as none of my servers have DVD/CD drives anymore).  Start setup process and select upgrade instead of custom.

    After about 30-40 mins, upgrade is done without a hitch.  First thing to do:  Go to all the individual VMs and update the integrated service packs!!!!!!

  • Hello,

    You're looking to upgrade the Hyper-V server product, vs. the full WS 2008 product, right?  I'd do the following:

    *  Delete any snapshots on the VMs.
    *  Export all VMs.  Make sure VMs are not on the OS drive.
    *  Install Hyper-V Server 2008 R2 and try upgrade if its an option.

    I've had great luck doing in-place upgrade on WS 2008 to WS 2008 R2 w/ Hyper-V role installed.  Not totally sure on the options for in-place with Hyper-V Server, but these steps would work with a clean install, provided the VMs are exported to a non-OS drive.
