System Center 2012 Service Pack 1 Upgrade Sequencing

If you have deployed any number of System Center 2012 products into your environment and are thinking of upgrading to Service Pack 1 (SP1) any time soon, then it is really important that you upgrade your System Center 2012 products in a particular sequence and that each of the products have first been updated to at least Update Rollup 2 (Cumulative Update 2).

The following list is the recommended upgrade sequence that should be followed for System Center 2012 SP1:

1. Orchestrator
2. Service Manager
3. Data Protection Manager
4. Operations Manager
5. Configuration Manager
6. Virtual Machine Manager
7. App Controller

Microsoft has recently released an on-line TechNet article that explains this sequence in detail and it's a must-read before you go ahead and deploy SP1.
