There are a few little tips that I have learned the hard way this week while getting ready for a server data centre move.
When migrating from a Virtual Server 2005 to a Hyper V server, you must ensure that you uninstall the Virtual Machine add on tools for Virtual server first.
If you do not, you will find that the Hyper V tools will not install until the other package is removed. And that mouse control is not available until these tools are installed. We all know what a pain in the rear end it is to work a Windows server without a mouse.
It is much easier if you do it as the last thing before shitting down the VHD before moving it.
