This week I finally found some time to upgrade my lab environment to SCCM 1511. My previous SCCM environment was running SCCM 2012 R2 CU4 so upgrading from this version was in the supported upgrade path so there was no need to apply any additional updates. If you are running any of the below flavours of SCCM you are good to upgrade to 1511:
- SCCM 2012 SP1
- SCCM 2012 SP2
- SCCM 2012 R2
- SCCM 2012 R2 SP1
If you are running SCCM 2012 then you should upgrade to at least SP1 in order to do an in place upgrade. SCCM 1511 can be downloaded from here. Once downloaded you will need to extract the files.
