SCCM 2012 SP1 to 1511 Migration RRS feed

  • Question

  • Hi,

    We are planning to do side by side migration from SCCM 2012 SP1 to 1511 with same tier hierarchy. Our current SCCM Hierarchy has 1 CAS and 2 Primary site Server. My questions is once we do side by side migration from top most hierarchy CASa to CAS do we need to run the same migration jobs on Primary also. Can you some please have your suggestion.

    Regards,

    Madhan

  • First, is there a reason you are migrating instead of just upgrading in-place?

    Next, if you still want to migrate, now's a perfect chance to get rid of that [nasty] CAS. If you have less than 150,000 managed systems, get rid of it.

    Finally, no to your question. You migrate global data -- basically, everything except clients are part of global data in ConfigMgr (there are a few smaller exceptions). Global data means it exists everywhere; i.e., on all primary sites, and that primary sites don't actually own any global data, the hierarchy does. Thus, you only need to migrate it once: from hierarchy to hierarchy.

  • Thanks Jason.

    The reason to go for side by side migration currently our SCCM 2012 SP1 environment is in windows 2008 R2 server for in-place upgrade we need to restore on separate hardware with Windows 2012 server which would require downtime. Also we are using CAS for centralized reporting and have two primary site to manage different region.  After we migrate hierarchy to hierarchy is it possible to have the same hierarchy structure ?

  • "is in windows 2008 R2 server for in-place upgrade we need to restore on separate hardware with Windows 2012"

    With version 1602 (released on Friday, you can now do an in-place upgrade from Windows Server 2008 R2 to 2012 R2.

    " CAS for centralized reporting and have two primary site to manage different region."

    This is an invalid reason for having a CAS and multiple primary sites. The only technical reason to have multiple primary sites as noted is if you have more than 150,000 managed systems or have very large amounts of clients (10,0000+ in multiple physical locations).
