How to Convert from Hyper-V to VMware
Windows 2008 server:
1. Insert the integration services setup disk.
2. From the command prompt (run as admin)
3. Run:d:\support\x86\setup /uninstall
It may give an "access denied" error when it's done, but it always does.
Leave the server up. 2008 will autoreinstall the Hyper-v integration tools on reboot, so DO NOT REBOOT. - stop all services that might result in clients connecting while you're doing the clone, such as SQL server, web sites, etc.
