Hi Solomon,
Please try to check replication between domain controllers.
repadmin /showrepl
If that is fixed you should be able to upgrade.

Please try to run "setup.com /prepareAD" and see the results.  If this command is successful you are ready to go.

Is there any failed/stale entry of corrupted AD?
If yes please try to clean (metadata cleanup) it up then you are ready to go.

Probably a domain controller replication issue.

Run DCDIAG on your domain controllers and fix any errors.
Post here if you have any questions about errors you may find.
