Hi All
I have a customer that wants to upgrade the OS of 4 EV servers from windows 2008 to windows 2012R2 ( these are Hyper-V VM)
Normally I would do an EV Server Move, create the new VM on the relevant OS and present the old EV storage, use the same name and run the EV setup. This always works
However the customer believes there are issues with presenting the storage using Hyper-V so they cant follow the normal option of an EV Server Move. They want to do an upgrade of the OS directly and I was wondering if this would work based on the following steps
Will this work and am I missing anything?

I guess the main question would be what support says?
I don't see a reason why it shouldn't work (if the in place upgrade is successfull) but there is that "should work" :)
I would still check why they can't move the storage.
If the storage is presented to the current VM's it shouldn't be a big issue to present them to a different VM.

Since they are VM's you can always take a Snapshot and roll back if needed. Have you seen this blog? https://blogs.technet.microsoft.com/chrisavis/2013/10/01/performing-an-in-place-upgrade-of-server-2008-r2-to-server-2012-r2/
Sounds like it might work.

personally, i've had nothing but issues with hyper-v and snapshots. i wouldn't rely on them. rather take a full backup before you start.

Thanks guys, I appreciate the feedback
I'll proceed with the OS upgrade and let you know how it goes

I tried to upgrade the OS this weekend but didn't uninstall EV. However, I ended up with IIS issues. EVIndex, World Wide Publishing, Windows Process Activation services all would not start. When opening up IIS Manager 8 I received a CLSID errors as well.
I rolled back in vmware to 2008 R2 from a snapshot.
Should I try to uninstall the binaries as well as IIS first? Then upgrade? The uninstalling of the binaries is worrying me.
Should I not worry?
Thanks,
Gary

Hello Gary,
It is best to create a new entry, refer this thread, then wait for answers. Not many people look at already closed questions to answer.
but, to answer your question. If you uninstall EV, then upgrade the OS, then reinstall EV, you should not have issues. What you need to do is to re-install EV after the OS is succesfully upgraded (including any SP and/or hotfix you had applied). After installing it, start the Enterprise Vault Configuration. When you then enter the EXISTING sql server, the config programm will see it is the existing server, and configure it as it is supposed to be.
some documentation can be found here: How to move Enterprise Vault to a new serr

Hi Folks
Was there ever an official word from veritas on this?
Reason i ask is we have a production env of 4 EV server and 1 DB that needs to go from 2008 R2 to 2012 and ev11.0.1 to 12.
Obviously this would save us an awful amount of heartache in the process, but we would be wary if theres no veritas stamp on it. Have they release an official how to for this?

Hey mate,
We have recently performed similar OS upgrade in a sizeable EV environment with 3 servers without uninstalling the EV and it worked fine. We even logged a case in advance, and support said there is no known issue about this. Hence, we proceeded and it all went fine.
Hope this helps.
