Having trouble finding out a proper way to do an in-place OS upgrade to 2012R2 for our existing Win2008r2 vCenter 5.1 update 1 deployment.
Windows 2012 is supported for vCenter 5.1 update 1, but would we have to upgrade to vCenter to 5.1 update 2 before updating the OS to 2012R2?
Has anyone does this or is building a new vCenter server based on 2012R2 and importing the database to a vCenter 5.5 update 1 install more practical?
