During a mailbox migration from Ex2010 to Ex2013, the Ex2013 server shut down unexpectedly. The database cannot be mounted anymore. About half of the mailboxes have completed the move to the Ex2013 database.
I've ran ESEUTIL /mh and it showed the database was in dirty shutdown state. Running ESEUTIL /r supposedly was successful, but the database still is in dirty shutdown state.
Because this happened the migration batch was running there was no backup of the Ex2013 database (would've run back up after the migration completed). The only backup we have is of all the mailboxes on the Ex2010 database before the migration batch was started.
Would there be any issues restoring the Mailboxes that were already moved to Ex2013 with backup from when those mailboxes were still on Ex2010?
