I'm in the process of researching upgrading our Enterprise Geodatabase. Historically, our current 10.7.1 geodatabase wasn't well maintained, so we are looking at taking a start from scratch approach instead of cleaning up and upgrading our currently EGDB.
That being said, we are currently on Enterprise 11.4, with hopes to upgrade to 11.5 in the fall/winter season. Is it possible to run 11.4 on an 11.5 EGDB, if i just create a new EGDB through Pro 3.5/EGDB 11.5? Or would it be best practice to create the EGDB with match the current Enterprise/ArcGIS Server Clients that we are running?
