EV Journailing Stopped after Migration

At the weekend we did a migration from EV9 to EV10.0.4 and used the migration wizard to do it.

After the inital migration did some checks for searching and retrieval and everything looked good.

So ran the backup's to make sure everything is good and then today I look and the Journal isn't archiving.

I found the Event ID 41111 -  "Error: Failed to resolve duplicate legacyDN for mbx"

I've looked at the TECH74074 and ran the SQL command and found 2 entries. Both linking to the same Default Vault ID.

MBXIndenty = 783 and 892

How do I know which one to delete?
