Hi We are running Exchange 2010 SP1. We have the following set up: 1 DAG split between London and Paris. DAG has 6 servers, 3 in each site. We have about 80 databases altogether. Two of the servers are lag servers. We performed some maintenance on one of the non-lag servers, to the DB's are distributed unevenly between the remaining 3. WHat's the best way to get all the DB's back to their Preference 1 server? Surely, we don't need to go through each DB and move manually?

Run RedistributeActiveDatabases.ps1 script to re-balance. Its located under the scripts directory http://technet.microsoft.com/en-us/library/dd335158.aspx Look under the section called: Balancing Database Copies
