ConfigMgr 2012 RTM to R2 Upgrade checklist

There are a number of good articles on how to upgrade from ConfigMgr 2012 RTM to Sp1, and from Sp1 to R2. If anyone needs to upgrade from RTM to R2, here are the steps:

Note: that the upgrade was performed on a single site, SQL Server was local, and on Server 2008 R2.  OSD was not in use. WSUS used a SUSDB database on SQL Server.

    Review system status/heath check – the ConfigMgr 2012 site was given a clean bill of health, with the exception of native SQL backup missing the ConfigMgr database. This was corrected.

    Backup – reviewed and corrected backup strategy for ConfigMgr 2012. Starting with ConfigMgr 2012 Sp1 and later, only native SQL Server backups are needed. (For more information, see: ConfigMgr 2012 Site Backup and Recovery)

    SQL Server database optimizationImplement Ola Hallengrens’ script; index & statistic optimization plan, to run 1x/week on all user databases. The benefit of this optimization, SUSDB will process updates faster, and ConfigMgr database optimization will benefit console users and update processes.

    ConfigMgr 2012 SP1 Upgrade – using installer, download all ConfigMgr prerequisites locally.

    Note:

    In SCCM 2012 the download pre-reqs command is:

    SetupDL.exe <target dir>

    The SetupDL.exe file is located in the SMSSETUP\BIN\X64 directory.

    Install ADK 8.1 – (ADK – required for Sp1 & R2 upgrade: select deployment tools, Win PE & USMT)

    Note: if the ADK was previously installed, an uninstall would be required here…

    Run SP1 installer upgrade – verify upgrade was successful by checking console version, and sitecomp.log.

    Backup SQL Server DB

    SQL Server upgrade – SQL Server was presently at SQL Server 2008 R2, decision was made upgrade to SQL Server 2012 Sp1, then apply SQL Server 2012 Sp1 Cu9

    ConfigMgr 2012 R2 Upgrade – using installer, download all ConfigMgr prerequisites

    Run R2 upgrade – verify upgrade was successful by checking console version, and sitecomp.log.

    Run R2 CU1 – verify upgrade was successful by checking console version, and sitecomp.log.

    Client Update – ConfigMgr 2012 RTM to R2

    Enable Automatic Site Hierarchy client upgrade – this upgraded the clients directly from RTM to R2.

    ConfigMgr R2 Cu1 Update – verified update.

    Create client deployment to upgrade clients from ConfigMgr R2 to R2 Cu1 – x64 & x86.

Post deployment, Software Updates refused to synchronize.

The WCM.log file will indicate:

Checking for supported version of WSUS (min WSUS 3.0 SP2 + KB2720211 + KB2734608)

Supported WSUS version not found

Resolution: These WSUS updates needed to be deployed post ConfigMgr 2012 SP1 to correct the supported WSUS version failure.

The updates are:
