SCCM 2007 Migration to SCCM 2012

    Question

  • I'm looking at upgradding SCCM 2007 to SCCM 2012 and I can't find the the answer to some questions

    1) Can I install SCCM 2012 onto the same hardware as SCCM 2007 so that way when I'm done the migration I can uninstall SCCM 2007.

    2) How do I decommission the old SCCM 2007?  is it just a Matter of Uninstalling it?

    Thanks

  • I don't know if this is in the docs, but you can't run two sites on the same OS. It doesn't matter why. It's just not possible. Just insert the CM12 DVD and run setup.exe. It will tell you that you can't install it because another CM instance was detected.

  • Here's the complete TechNet migration documentation which explicitly details standing up new hardware for the new 2012 site: http://technet.microsoft.com/en-us/library/gg699364.aspx

    Documentation is generally inclusive in that it only discusses what can/should be done. It can not be exclusive because that is usually unbounded/limitless; however, generally, if it's not included it means you can't/shouldn't do it.

    Ultimately, not everything is or can be documented: http://technet.microsoft.com/en-us/magazine/jj643252.aspx

  • #1: no. You have to use a separate server
    #2: uninstall and shutdown the old server. Clean up the System Management container in AD, DNS and WINS entries (depending on your current configuration). Make sure to upgrade and re-assign the clients which implies to use a different site code.

  • So there is no way of running SCCM 2007 and SCCM 2012 side by side on the same machine?

    Shoot.. that puts a monkey wrench in my plans...

    thanks

    Actually, the monkey wrench was putting together a plan without knowing the facts.

    </be> With all due respect I wasn't doing anything without knowing all the facts. That is why I posted before I actually started doing anything because I didn't know and wanted to find everything out before I did anything The monkey wrench part is because my boss told me he wants it on the same system as the 2007 version. So I have to make him understand that Thanks to everyone for their posts

  • Is there any official MS documentation that says why and the reason I can't install SCCM 2012 on the same hardware as SCCM 2007 at the same time for Migration Reasons...

    My Boss want's to know why and I can't find much documentation as to why

    Thanks

    Great thanks... that is somewhat I was looking for.. I haven't yet had the chance to try as I can't until I present all info to my boss...  I really wish MS would put out better documentation.

    Thanks Again

  • Thanks Jason.. I do understand that they can't document every possible scenario.. but I was thinking more of a general -  You can't do an inplace upgrade (which is very obvious) and you MUST use awhole other server..

    As you can tell I'm VERY NEW with System Center.. and I've been told to learn it and know it all components inside and out..   I guess I"m used to when new versions of  exchange come out saying Yes must be installed on a second server.. and No there is no option to install exchange side by side of another.

    Thank you to the forum and to those of you that know this stuff that makes it easier to get through.

  • From http://technet.microsoft.com/en-us/library/gg681981.aspx :

    "You must first install a System Center 2012 Configuration Manager or System Center 2012 R2 Configuration Manager hierarchy to be the destination hierarchy before you can migrate data from a supported source hierarchy."

    Also, please go back to whomever set the ridiculous expectation that you learn System Center inside and out and ask for a huge raise (like 500%) or tell them it can't be done and you are being set up for failure. Many of us have been at it with just ConfigMgr for 10-15 years and would never say that we know it inside and out. ConfigMgr is far too big of a product -- also note that when you say "System Center" I assume you mean "ConfigMgr"; System Center is a suite of products that ConfigMgr is part of.

  • I already run SQL Server 2008R2 with a few instances on it.   when I install SCCM 2012 on a new machine, do I need to install a second SQL server for the new SCCM 2012 or can I use my existing SQL server 2008R2 and just run another instance off of it.

  • Yes, you *can* add additional side-by-side instance of SQL Server regardless of version. You cannot use an instance of SQL Server that already has DBs in it though.

    Whether you *should* is another story. Local SQL for ConfigMgr is generally a better choice. Also, ConfigMgr is not your typical application, it requires a significant amount of resources on the SQL Server so putting it on a shared SQL Server *will* impact the performance of the other instances and applications sharing that server and of course your ConfigMgr installation may be sluggish.
