SCCM 2012 R2 UPGRADE



Upgrade for System Center 2012 Configuration Manager to Cumulative Update 1

Upgrading Central/Primary Server

  • Ensure all sites in the hierarchy run System Center 2012 Configuration Manager with R2.
  • Ensure the computing environment meets the supported configurations that are required for upgrading to System Center 2012 R2 Configuration Manager CU1.
  • Review the site and hierarchy status
  • Disable database replicas for management points at primary sites.
  • Back up the site database at the central administration site and primary sites.
  • Disable all site maintenance tasks at each site for the duration of that site’s upgrade.
  • Close an open Configuration Manager console before the upgrade. The installation process cannot upgrade an open console.
  • Run the Upgrade on the Primary Site to verify the prerequisite checks:
    • Verifying update applicability
    • Verifying Restart is not required
    • Verifying no active Configuration Manager Console is open
    • Verifying SQL connectivity

  • The update automatically upgrades the database
  • To manually update a site database, use SQL Server Management Studio to connect to the site's SQL Server, and then run the update script named update.sql on that site's database. When the update bundle installs, it extracts update.sql to the following location on the site server:

\\<Server Name>\SMS_<Site Code>\Hotfix\<KB Number>\update.sql.


Post Upgrade Activities

Automatic actions: Post upgrade the below actions are triggered automatically
  • To complete the Upgrade successfully the server needs to be rebooted.
  • The site performs a site reset, which includes a reinstallation of all site system roles.

Manual actions for the administrative user after an upgrade:


  • Distribute content for the new Configuration Manager client packages
  • Ensure that clients that are assigned to each primary site upgrade and install the client software for the new version.
  • Upgrade each Configuration Manager console that connects to the site and that runs on a computer that is remote from the site server.
  • At primary sites where the database replicas for management points runs, reconfigure the database replicas for System Center 2012 R2 Configuration Manager CU1. 


Upgrading Secondary Server

  • Ensure all Secondary Server are on SCCM 2012 R2
  • Review the site and hierarchy status and verify that there are no unresolved issues.
  • Disable all site maintenance tasks at each site for the duration of that site’s upgrade.
