We have a pretty new, not yet production, AD Connect setup. When reading through install requirements we understood that once our environment goes production we will probably hit the 100,000 synced objects and should probably deploy AD Connect with a dedicated SQL database an another system.
We are currently only syncing with the group filter options for testing. AD Connect is version 1.5.45.0. Could I still do an in-place upgrade to the new 1.6.4.0 build, or would I have to go through the hassle of deploying a second staging server and doing a cutover?
