Step By Step Guide to Migrate SCCM 2012 R2 to SCCM 1511

Upgrade Checklist:

  1. Ensure that your computing environment meets the supported configurations
  2. Review the site and hierarchy status and verify that there are no unresolved issues:
  3. Install all applicable critical updates for operating systems on computers that host the site, the site database server, and remote site system roles:
  4. Uninstall the site system roles not supported by System Center Configuration Manager, if any   i)Out of Band Management point    ii) Service Health Validator point
  5. Disable database replicas for management points at primary sites.
  6. Disable all site maintenance tasks at each site for the duration of that site’s upgrade.
  7. Run Setup Prerequisite Checker.Before you run Setup to install or upgrade a site, or before you install a site system role on a new server, you can use this stand-alone application (Prereqchk.exe) from the version of Configuration Manager that you want use to verify server readiness. The use of prerequisite checker enables you to identify and fix problems that would block an actual site or site system role installation.Note: Prerequisite checker always runs as part of Setup.It logs its results in the ConfigMgrPrereq.log file on the system drive of the computer.
  8. Create a backup of the site database at the central administration site and primary sites.
  9. Test the database upgrade process on a copy of the most recent site database backup
  10. Restart the site server and each computer that hosts a site system role to ensure that there are no pending actions from a recent installation of updates or from prerequisites:

Let’s Start:

Step 1: Disable SQL replication

If you are running replica MPs, then you will need to disable SQL replication. Load up SQL Management Studio.

Drill down to Replication, right click and choose ‘Disable Publishing and Distribution’


Click Next


Select ‘Yes, disable publishing on this server’ and click Next.


Confirm the dropping of replication by clicking Next.


Ensure ‘Disable publishing and distribution’ is checked and click Next.


Click Finish to disable the replication.


Click Close to complete the process.


Remember to re-enable replication once the upgrade to 1511 is complete.

Step 2:  Remove Windows ADK install

My ConfigMgr site server is currently running Windows 8.1 ADK. Uninstall this release from the Control Panel


Click yes to uninstall


Click Close when complete


Step 3: Install the Windows 10 ADK

Download the Windows 10 RTM ADK release 10.0.26624.0 from here

Note: I will prefer having offline setup for installing the ADK setup

Run the adksetup.exe file.adk-4.jpg

Click to install the ADK files into the default path. Click Next.


Decide whether to add Windows Kits to the system. Click Next.


Accept the ADK license agreement.


Select only Deployment Tools, Windows PE and USMT components for installation.

Click Install.adk-8adk-9

Click Close when complete


Step 4: Install KB3095113

Download and install hotfix KB3095113 on your SUP before you start the upgrade

Step 5: Backup and TestDBUpgrade

Before upgrading, perform a backup of your SCCM database.

It is recommended to test your Configuration Manager database before the upgrade.

Backup your site database , Restore it on a SQL server running the same version as your SCCM SQL instance.

On the SQL server, run the SCCM setup command line using the Testdbupgrade switch

Open the log file on C:\ConfigMgrSetup.log

If the process is successful, you can delete the database copy

If you have errors, resolve them on your SCCM server, do a new backup and restart this procedure.db.jpg

After you successfully upgrade a copy of the site database, proceed with the “real” upgrade.

Step 6: Review the site and hierarchy status

Review the site and hierarchy status and verify that there are no unresolved issues

Step 7:  Uninstall 3rd party SCCM Console Extension

If you have console installed on the site server, remove any 3rd party extensions (you should not have it anyway)

Step 8: Reboot Server

Step 9: Run SCCM Prerequisites

Download SCCM Pre-requirements (use setupdl.exe)

Note: Prerequisite checker always runs as part of Setup.

Step 10: SCCM 1511 Upgrade Installation

Close all running consoles on the server. Check also if remotely logged users are running the console in their sessions. The setup won’t check that and you’ll end up having an error in the installation log at the end of the process.

ERROR: Configuration Manager Console uninstallation failed. Check log file ConfigMgrAdminUISetup.log.

Step 11: Verification

Once the setup has completed, there’s a couple of checks that you can make to be sure the upgrade process was successful.

C:\ConfigMgrSetup.log – Display detailed installation steps. verf.jpg


On your Site server check the value called Full Version, found under HKLM\Software\Microsoft\SMS\Setup. It should read 5.00.8325.1000. In addition to the Full Version value, the CULevel should now be set to 0. verf-1.jpg
