Waynards,
I have also open a ticket with support, as I cannot find docs on how to perform this OS+SQL version changes (Win2008R2 to Win2012R2 and SQL2008R2 to SQL2012).
Thanks for the tips on your previous post.
If I hear anything else from support I will update this thread.
Forgot to ask: Did you keep same hostname+IP address on you new vCentre???
