Migrating from SCCM 2007 SP2 to 2012 R2 RRS feed

  • Question

  • Hi

    in our organization we have just one primary site and two DPs and database is in the seperate server. it's sql server 2008 r2

    I want to first remove the existing sccm 2007 and then clean install the 2012 r2 version. I have some questions about that:

    1- Can I use the same site code after removing older version?

    2- what happens to the clients? after installing the new 2012 console and setting boundaries and other settings , the clients will get updated to new version without any problem automatically?

    3- we don't have much configurations and i prefer to do a clean install of sccm 2012 r2. do you recommend doing this instead of migration plans?

    thanks a lot

  • 1) the sitecode has to be unique. You can't have to same one at the same time.

    2)  you have to either push the client from CM12 or install the CM12 one using CM07 or whatever method you prefer. This does not happenautomatically.

    3) it depends. You can uninstall CM07, clean up DNS / AD and install CM12 (even using the same site code in that scenario), but you won't be able to migrate old stuff then.

  • You have to clean up the System Management container after uninstalling ConfigMgr 2007.
    Installing the CM12 client will automatically uninstall the 07 one.
    It does not matter if physical or virtual as long as the machine has got enough resources.

    First of all, I don't want my stuff on the CM07. I don't need them anymore.

    Second, in CM07 I created a batch startup file in the active directory to setup the client. If i do the same for CM12 client, will it replace for the old client successfully? 

    the only thing that i'm worried about is these:

    1- by uninstalling the CM07 it doesn't  left some data into my DC

    2-by installing the CM12 the client's could be adapted to the new version.

    3-now i have multiple services on the current SCCM Server which is a physical server and i want to install the new version into a VM mechine running on our ESXI server. I hope things work in the new server.

  • thanks Toresten

    Just one another question, could you provide a useful link for uninstalling CM07 completely without any leftovers?

  • Just uninstall it from the Control Panel on the 2007 site server. This should cleanup up the System Management container but you can also delete its contents manually. That's it. In fact, you don't really have to even run uninstall if you don't want, but just clean up the system management container.

    There are other small possibilities of items that are rarely done like Group Policy and DNS but these only need to be cleaned up if you've enabled or customized them.
