This week I finally found some time to upgrade my lab environment to SCCM 1511. My previous SCCM environment was running SCCM 2012 R2 CU4 so upgrading from this version was in the supported upgrade path so there was no need to apply any additional updates. If you are running any of the below flavours of SCCM you are good to upgrade to 1511:
- SCCM 2012 SP1
- SCCM 2012 SP2
- SCCM 2012 R2
- SCCM 2012 R2 SP1
If you are running SCCM 2012 then you should upgrade to at least SP1 in order to do an in place upgrade. SCCM 1511 can be downloaded from here. Once downloaded you will need to extract the files.
Before upgrading there are a number of prerequisites to consider:
- If you have a multi-site hierarchy with a Central Administration Site and multiple Primary Sites, you need to start at the top of the hierarchy and work down
- Install ADK version 10, this can be downloaded from here
- Install this WSUS hotfix to the server that is hosting your SUP. You only need to do this if you’re planning to use Windows 10 Servicing. This hotfix is only available for Windows Server 2012 or Windows Server 2012 R2.
- If you have database replication enabled on your Management Points disable this and set the management point database back to Use this site database
- Close all running consoles on the server and remotely
- Ensure you have a current backup of your SCCM site
Time to upgrade
- Browse to the location that you downloaded and extracted the installation files to and launch Splash.hta.
- Click Install
- If prompted, click Yes to allow the program to make changes to this computer
- On the Before You Begin screen, click Next
- On the Getting Started screen check that Upgrade this Configuration Manager Site is selected and click Next
- On the Microsoft Software License Terms screen, select I accept these license terms and click Next
- On the Prerequisite Licenses screen, select all check boxes and click Next
- On the Prerequisite Downloads screen, enter a path to download the files to and click Next
- At the Server Language Selection screen, click Next
- At the Client Language Selection screen, click Next
- At the Usage Data screen, click Next
- At the Service Connection Point Setup screen, click Next
- At the Settings Summary screen, click Next
- At the Prerequisite Check screen verify that you don’t have any errors and click Begin Install
- Once the install has finished click Close
Once the upgrade process has finished, you can verify that the installation completed without errors my viewing the ConfigMgrSetup.log in the root of the c:\ drive. At the bottom of the log you should have the line Completed Configuration Manager 2012 Server Setup – Upgrade (note that it still says 2012). You can also verify that the upgrade completed by opening the console and selection About Configuration Manager from the blue arrow menu.
In addition to upgrading the site to 1511, the Boot images and Configuration Manager client package will also have been updated to the latest versions provided by the updated ADK installation.
Post Upgrade Tasks
If you have other sites in your hierarchy, these should now be upgraded also, again you should follow the top downwards process. If you have a Intune subscription configured, this role should be reconfigured. If you were using database replicas for your Management Points remember to re-enable this once all sites are upgraded. Finally once all your sites are upgraded you will need to update your clients and the console on any remote servers or workstations.
