Getting ready

Go through the Checking the VMM system requirements and preparing for the upgrade recipe after deciding the upgrade method (in-place upgrade or upgrade to another server), and make sure you've installed all of the prerequisites.

If you're planning an in-place upgrade of VMM 2008 R2 SP1 running on a server with an OS other than the supported version, first upgrade the OS, and then carry out the steps to upgrade to VMM 2012, as described in this recipe.
