Can I do a in place upgrade of Windows Server 2008 Standard to R2 Enterprise

I have a Windows Server running 2008 standard edition. It's running Hyper-V and hosting about 12 virtual machines. This server also has a MD1200(Dell direct-attached storage) attached to it where all the .vhd's are located.

I need more ram so I would like to do an in place upgrade to 2008 Enterprise R2 so I can get past the 32gb limit. Are there any problems doing this?

Will I break Hyper-V?

Will all the currents roles and features be retained?

Anything else I need to watch out for?

Thanks...

Yes, you can do an in-place upgrade from 2008 to 2008 R2.   There shouldn't be any issues andit won't braek Hyper-V.

There should be no issues in completing this and the current roles and features will be retained as long as you select an upgrade install during the initial boot.

However - that being said, I would still create a backup of the server - Just in case...
Agreed, DEFINITELY take a full backup before performing any upgrades.

The upgrade did wipe out all my VM's, but the vhd's were safe. Basically had to rebuild all my VM's from scratch and reconnect tem to the VHD's
