My last post in this space was on 2012/08/09. I thought this is good time to post another helpful tips on SCCM 2012 R2 upgrade with a checklist. Now we start planning the upgrade from SCCM ConfigMgr 2012 Sp1 to SCCM 2012 R2. As First step, I would perform is download all the binaries including Windows ADK 8.1, Prerequisite Files for ConfigMgr R2 and CM2012 R2.
ConfigMgr SCCM 2012 R2 Upgrade Checklist
- All the sites in the hierarchy must have ConfigMgr SCCM 2012 SP1. If you’ve not upgraded SCCM 2012 RTM to SP1. Have a look at the SP1 upgrade checklist here.
- Top to Down approach. Need to upgrade the CAS server (if you’ve one) first then primary and it’s secondary servers.
- No need to update remote Site System servers (remote DPs, MPs, SUPs). However, ensure that prerequisite for installed site system roles.
