We just updated to UN v5 and have hit a brick wall. Here is what we did:
Update Pro to v2.7.2
Upgrade Enterprise to 10.9
Upgraded the EGDB
Undated untools in Pro to v2.7
When trying to stage the UN, we get this error. Doesn't make sense, since we did all of the upgrades. And we had v10.8 in the first place, so anything below v10.7 wasn't even a factor.
ERROR 003320: The connected portal's federated servers do not meet the minimum supported release for the Utility Network - 10.7
