I had a win 2008 64 std and needed to upgraded it to R2. It had hyper-v (has win 2003) before the upgrade which I just stopped. It was giving me a warring to remove, but I did not. I have copied th .vhd file and did the upgrade.
Now the hyper-v network is not working so I stopped it and remove the rule and I am reinstalling it again.
after installing it I can just move the .vhd file and it should work? or do I have to do any other configurations. thanks!
