Adding replacement EX16 server and moving users

jeff mcnabney 301 Reputation points

Existing EX16 CU9. Added second EX16 CU19 server to replace EX16 CU9 (currently offline) on same subnet and same AD. New CU19 is mostly configured for operation. How do i port users from old CU9 server to cu19 server. Am i to understand that i cant do a mailbox move? It seems that the CU9 server is the primary and mail is flowing through it. Sending from a test mailbox on CU19 gets stuck in the queue even though the send connectors are active and i can ping the destination relay. I've seen it suggested to create a DAG (which i have never had to do before) and seed the databases, and then make the new server the primary. I have no idea if this will work. Under the gun here to get mail back online asap.

    Yes I have experience with that and know Jaap personally. :)
    You can trust his procedures and you can use that technique and rebuild the CU9 server - then restore from backup
