Join Google + Page – Google+ Community

Finally, SCCM ConfigMgr 2012 R2 RTM version has been released. More details about ConfigMgr 2012 R2 download here. Now start planning the upgrade from SCCM ConfigMgr 2012 Sp1 to SCCM 2012 R2. First step, I would perform is download all the binaries including Windows ADK 8.1, Prerequisite Files for ConfigMgr R2 and CM2012 R2.

SCCM ConfigMgr 2012 R2 CU1 has been released. Download and keep it ready to apply CU1 to post R2 installation. Download SCCM Configmgr 2012 R2 Cumulative Update CU1 – See more at: http://anoopcnair.com/2014/03/28/download-sccm-configmgr-2012-r2-cumulative-update-cu1/

List of Post SCCM ConfigMgr 2012 R2 Hotfixes

If you’re wondering what are the added features, changes and bug fixes (R2 is basically a feature pack but in SCCM 2012 R2, probably we can see loads bug fixes also).  Here is the direct links to technet library about new stuffs included in SCCM R2 Site Installation and the Configuration Manager Console , Sites and Hierarchies, MigrationClient Deployment and OperationsSoftware Deployment and Content Management and Monitoring and Reporting.

ConfigMgr SCCM 2012 R2 Upgrade Checklist

Make sure you’ve all prerequisites in place. More details about prerequisites are here.

  1. All the sites in the hierarchy must have ConfigMgr SCCM 2012 SP1. If you’ve not upgraded SCCM 2012 RTM to SP1. Have a look at the SP1 upgrade checklist here.
  2. Top to Down approach. Need to upgrade the CAS server (if you’ve one) first then primary and it’s secondary servers.
  3. No need to update remote Site System servers (remote DPs, MPs, SUPs). However, ensure that prerequisite for installed site system roles.
  4. 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.
  5. Uninstall Windows Assessment and Deployment Kit (Windows ADK) 8.0 from SCCM ConfigMgr 2012 SP1 Site Servers.
  6. Download and Install Windows Assessment and Deployment Kit (Windows ADK) 8.1on SCCM ConfigMgr 2012 SP1 Site Servers. Download Windows ADK 8.1 from here. .Net 4.5 Framework required for Windows ADK 8.1 . Restart may required after .Net 4.5 installation.
  7. Disable the site maintenance tasks “Backup Site Server”, “Delete Aged Client Operations” and “Delete Aged Discovery Data” on SCCM ConfigMgr sites.
  8. Ensure removed MP replicas and if you’re using SUP with NLB then reconfigure it.
  9. 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.
  10. Download prerequisite files and redistributable files well before scheduled time of SCCM ConfigMgr 2012 R2 upgrade which are the required for ConfigMgr 2012 SP1.
  11. Check SQL version of DB server and confirm this supports SCCM 2012 R2.
  12. For existing SCCM ConfigMgr 2012 SP1 secondary SQL express DB, make sure that SQL Server 2012 Express cumulative update 2 (CU2) has applied before upgrade of ConfigMgr 2012 secondary site servers.
  13. Take a copy of SCCM ConfigMgr SP1 2012 DB and attach it to a test SQL server and run test the database upgrade.
  14. ConfigMgr SCCM 2012 R2 upgrade will automatically distribute update for default client installation package and new Windows ADK 8.1 boot image. So if you’ve loads of remote DPs in the environment then don’t get suprised with these new updates. Plan this well advance.
  15. Make sure SCCM ConfigMgr 2012 Site Servers including remote DPs, MPs, SUPs etc are restarted if this is required.
  16. Reconfigure replica MPs, NLB SUPs and re enable the DB maintanance task which are disabled.
  17. Make sure all the SCCM ConfigMgr 2012 consoles are running with R2 version.
  18. Plan and update/upgrade SCCM ConfigMgr 2012 SP1 clients to SCCM 2012 R2.

    Hello,

    As always you have done great work. I have a Windows Server 2012, SQL 2012, and CM 2012 SP1 system. Which would I upgrade to R2 first? The OS or CM?

    Thank you,
    Matt

  2. Matt says:

    Hi Anoop,

    Thanks for your suggestions and your blog is very informative and helpful.

    We are planning for the Upgrade from SCCM 2012 SP1 to SCCM 2012 R2 CU1 and possible hotfixes in the live environment . we have concern with the following possibilities

    1)Roll Back Plan if the Upgrade fails
    2)We use OSD so from Microsoft we got to know that we have to update the boot images as well .does this updating boot image will also apply to custom boot images which are currently in production.
    3)SCCM Clients – In our test VM we had to reinstall SCCM client in a test client machine after the upgrade .so if this happens in the live environment it will be difficult to reinstall such a large number of clients
    4)Pre and post upgradation checks that has to be done.

    Thanks in Advance
    Vinay Shivashankar

      Only supported role back plan is to backup and restore.
      If I’m not wrong it won’t happen to custom boot images.
      In normal scenarios you don’t need to re install the clients

  5. sandip says:

    Can I upgrade my site to R2 Cu4 and leave client on SP1 CU3. Would client be able to talk with site?

    • Anoop says:

      I think this should work. But I don’t think that is a good idea to leave client with old version. Most of the fixes in the latest versions have client component as well. So those fixes won’t work until you upgrade your clients to latest version.

    I am upgrading SCCM 2012 SP1 CU5 to SCCM 2012 R2 SP1 CU2. Is it possible to upgrade the SCCM Client agent on workstations using any SCCM Client Patch, as it is not created by default after the upgrade. When I created it manually and tried the deployments for hotfix KB3100144, it throws an error code 1642 that related product is not installed. When I tried client Install for one machine, it successfully upgraded the client version.
    Is there any other method for upgrading the client agent instead of FULL client upgrade like using patch (.msp).
