Hi All: We have added a new Exchange backend server in the current setup and tried moving a test user mailbox using ESM. The process was completed successfully. However when we are trying to check the same using OWA it is giving "HTTP/1.1 503 Service Unavailable". Please help me on this.

Make the new server Exchange 2007 . Read: http://www.msexchange.org/tutorials/Transitioning-Exchange-2000-2003-Exchang e-Server-2007-Part1.html or similar articles that cover migrating to E2k7 and retiring your E2k7 servers . Recommend going with a CCR cluster, which requires at least 3 E2k7 server (CCR node 1, CCR node 2, HUB & CAS server) o If you call all-in-one then HUB, CAS, & MBX roles can be on one system . If you don't go CCR then at least setup LCR . If you do goto E2k7, you will need to replace your FE with a E2k7 CAS server before you move mailboxes to E2k7 2. Recommend adding at least one addition DC.

I will recommend you to distribute the mailboxes, so everything should go ok.

The only con is probably to considering migrating to 07 which will give you a that significant IO reduction via incremental memory.

We are planning to add an additional backend server with higher disk and I/O capacity and move the mailboxes on the new server. The steps are broadly outlined as below: 1. Additional Server joining the Existing windows domain 2. Installing Exchange server joining the Existing Exchange Organization. 3. Creating Multiple Mailbox Stores to distribute Mailboxes between stores. 4. Moving mailboxes to a New Exchange Server Can somebody please guide me through the pros/cons of this setup or pre-defined checklist that one needs to take care of in this kind of migration.
