Few Eye Catching Bullet Points

1. Top to Down approach. Need to upgrade the CAS server (if you’ve one) first then primary and it’s secondary servers.

2. Take backup of CAS as well as Primary servers. Ensure that you’ve a good copy (I would suggest to have 2 copies just in case) of backup.

3. Install Windows Assessment and Deployment Kit (Windows ADK). Available here.

4.Disable the site maintenance task “Delete Aged Client Operations” on primary sites. This is interesting step, this is the first time I’m hearing about it. More details are available in the following TechNet link.

5. Create a copy of all the build-in collections IF you’ve modified those. In ConfigMgr 2012 SP1 the built-in collections are read-only and cannot be modified. Isn’t that interesting?

6. Run the prerequisite checker, 1 or 2 days prior to the actual upgrade. It would be easy to identify whether there is any issue with prerequisites or not.

7. Download prerequisite files and redistributable files which are the required for ConfigMgr 2012 SP1.

8. Take a copy of CM 2012 DB and attach it to a test SQL server and run test the database upgrade.

9:  WSUS patches KB 2720211 and KB 2734608 need to be installed on CAS, primary and remote SUP servers (Creation of SUP will fail without these updates applied to WSUS).  Thanks to Mike !

10. Uninstall previous version Windows Automated Installation Kit (AIK) from the server before installing new version.

11.  Go through the KB article 2801416 to understand the process that we need to follow before SP1 upgrade.

12. Apply the following hotfix 2801987 before upgrading ConfigMgr 2012 SP1 Client.
