Windows 2012 RC Upgrade to Stable

We deployed a handful of servers running on Windows Server 2012 Release Candidate, unknowing that it was the RC -- we had believed it was the actual Release-to-Market version.

Now, the first one setup is rebooting every hour because apparently the RC version starts doing that after some weeks of usage.

How can I upgrade this to the RTM release without reloading these servers? The work to backup the data, reload the servers, etc, will be extensive and anything we can do to avoid it will good.

The normal boot into working OS and then insert the new RTM disk, and then do an upgrade after you edit the cversion.ini to MinServer=8400.0. This is not the ideal solution though but it may work...  there are many locations that you can export the current server configuration and then use powershell to import the exported config.
