It seems very odd to me that I can’t join 4.3 to 4.1_5.
Is this true for all backwards joins?
Typically major upgrades aren’t done on live servers. It’s best practice
to create a new domain controller, join it to the domain, the transfer FSMO roles, then
decommission the old server. It seems this “best practice” is not possible with UCS.
Are there any newer versions that can join older versions? Am I trying to skip too many
major versions? Is there a way to force the join or bypass the version check?
4.1_5 is too old to run the upgrade in place, and I can’t join 4.3 to it.
Seems like I’m between a rock and a hard place.
