When you capture a base layer for Windows 7, Windows 8.1, or Windows 10 migration using Microsoft System Center Configuration Manager (SCCM), certain preparatory steps must be performed.

About this task

The reference machine must not be rebooted, and the ccmexec service must not be restarted during the time between performing the procedure and capturing the base layer.

Regular base layer updates do not require these steps, as this is already handled by Mirage.


  1. If SCCM client is not yet installed, manually install the client following the instructions at http://technet.microsoft.com/en-us/library/bb693546.aspx.

    Do not specify a SCCM site code for the client in the CCMSetup.execommand-line properties (SMSSITECODE parameter).

  2. Stop the SMS Agent Host service (net stop ccmexec).
  3. Use ccmdelcert.exe to delete the SMS certificates. ccmdelcert.exe is available as part of the Systems Management Server 2003 Toolkit, and is also attached to the wiki page.
  4. Delete c:\windows\smscfg.ini if it exists.
  5. Capture a base layer.

    Do not reboot or start the ccmexec service. Otherwise you must repeat this procedure.
