Hi Jeff,
I'm in a similar situation where I just joined a new company and have to upgrade the existing 2012 RTM environment and I'm thinking it's going to be easier to set up a new 1702 installation from scratch rather than upgrading multiple times. Did you run into any issues standing up a new instance of SCCM with an existing, like using the same System Management container, etc? Or anyone else who may have been through this/have knowledge to share on the process?
Thanks!
