I have recently dismissed a 2012 DC and replaced with 2016 in a subdomain.
At present replication of Sites and Services are not in sync between the 2 domains.
The main domain still sees an old servers in Sites and Services, and i cannot delete it.
Similarly in NTDSutil metadata cleanup I get a message that I should do this from a DC in the Subdomain, and the mentioned server is not removed, but is not presented in the Subdomain, when I connect to a DC in the subdomain.
Repamin /replsum gives me these errors since a few weeks, from any DC.
DC(name of dc in main domain) 19d.03h:18m:48s 1 / 6 16 (8464) Synchronization attempt failed because the destination DC is currently waiting to synchronize new partial attributes from source. This condition is normal if a recent schema change modified the partial attribute set. The destination partial attribute set is not a subset of source partial attribute set
The old DC Computer object and all DNS entries are removed from the Subdomain. But the main domain DNS still reports the old server entry in the Subdomain NS (non removable).
How to cure the situation?
