Thank you all. Really useful information. I also need to move my SCCM2012 R2 server (SQL on a diff box) from Winserver 2008 to 2012 but have a dilemma. I want to upgrade SCCM to SP1 but I'm not sure if should do the upgrade first and a few days later do the move or do the move first and later the upgrade. What is recommended to do first?
Thanks
