I am upgrading my client's primary site server from SCCM 2012 R2 with no CU to SCCM 2012 R2 SP1 tomorrow afternoon so that they can support Windows 10 clients. I have only had a few days to prepare and have been reading through blogs and faqs as much as possible.
I have obtained the source files for SP1 and prepared a lab with the same build version (2012 R2 with no CU) and I am running through the R2 SP1 upgrade as I type. It seems to be going well so far... I am looking for any feedback from those who have already done this upgrade? I find these types of posts helpful from the "real world" experiences that folks have had.
For example: were existing deployments impacted (software updates or apps)? Were any site systems impacted that required remediation after the update? Was there down time with any of the components after the upgrade? Were there steps you wished you had taken prior to the upgrade that would have made it easier? Were you able to manage Windows 10 clients afterward?
Any advice (positive or negative) is appreciated.
Thanks, FP
