Hello everyone,
I need to upgrade a windows server 2008 R2 standard (with Hyper-V and 10 active VM installed and configured) to windows 2008 R2 Enterprise and avoid reinstalling everything.
I read a couple of guides but I did not understand if they are official and make me safe from future problems or blocks.
