mikedisd Posted October 14, 2014 Report post Posted October 14, 2014 I need to perform a side-by-side migration of our existing CM12 SP1 system to CM12 R2. Which is preferable: Upgrade existing CM12 SP1 to R2 and then migrate to new CM12 R2 server; or Migrate to new CM12 SP1 build and then upgrade that to R2? The remote database will also be moved from a SQL 2008 box to SQL 2012 SP2. thanks Quote Share this post Link to post Share on other sites More sharing options...

mikedisd Posted October 14, 2014 Report post Posted October 14, 2014 The existing SCCM server is problematic and some components / services (WSUS, WDS) are broken, which I can't get working again. It's also Svr 2008R2 and we want to move SCCM to Svr 2012 R2. Quote Share this post Link to post Share on other sites More sharing options...
Peter van der Woude Posted October 15, 2014 Report post Posted October 15, 2014 I've heard that migrations also work when done from a SP1 site to a R2 site, but officially only migrations from the same version are supported. In that case I would start my new site as clean as possible, with as little as possible changes (meaning upgrades). So, I would start at R2 and upgrade the old also to R2. 1 Quote Share this post Link to post Share on other sites More sharing options...
mikedisd Posted October 16, 2014 Report post Posted October 16, 2014 Thanks for the reply, the existing server became a real mess when upgraded from RTM to SP1 (ie, EVERYTHING broke) so this makes a lot of sense. Thanks! Quote Share this post Link to post Share on other sites More sharing options...
