Today I upgraded my OpsMgr 2012 SP1 Beta environment to SP1 RTM. The upgrade process is not supported by Microsoft but works without any problems. The upgrade process of the server components completed in 45 minutes.
The original Operations Manager 2012 SP1 Beta version number was 7.0.8925.0:
The updated Operations Manager 2012 SP1 RTM version number is 7.0.9538.0:
Next is updating the clients and upgrading my Orchestrator 2012 SP1 Beta environment!
