In my current environment with 1 primary and 30 secondary site supporting up-to 4000 devices. Current version is SCCM R2 SP1
hosted on 2008 R2 servers. I am looking to upgrade the environment to current branch with server OS 2016.
My primary concern is to reduce the number of secondary sites. My plan is the convert most of these secondary sites to DPs and do an inplace upgrade to CM 1606 version. and then do a windows OS upgrade 2008 R2-> Server 2012 R2->Server 2016 and once
on OS 2016 do a inconsole upgrade to CM current branch
What are the pros and cons of this approach?
Your suggestions are much appreciated..
