I'm back again. So myself and another guy I work with have inherited the SCCM system from our predecessor who is no longer with the company. (hence all the SCCM related questions)
We are looking at upgrading to ConfigMgr 1810 from 1802. I'm doing some research to understand the process and make sure I am not missing anything major so that we can make this as seamless as possible.
Some basics about our setup:
-14 DP's of which 11 are Pull DP's
-1 Cloud DP
-Only run OSD from a single site - the Main SCCM site
-Have only recently begun expanding application deployment via SCCM, so minimal applications on the DP's at this point
-We have about 1500 clients installed including VM's, servers, and end user workstations
What I am wondering is what the major considerations we have to think about before we get this started. I'm speaking specifically to your experience and or resources. I have the MS TechNet upgrade checklist, back up procedures for the the site, and a step by step upgrade guide from System Center Dudes. We are planning on taking a snapshot of the SCCM server ahead of time to protect the system if it all blows up.
Would be great to get some insight from anyone with experience in this as I want to minimize the surprises (I know I can't eliminate them all) for this upgrade.
Thanks in advance! Looking forward to your insight!
