I am doing a migration of mailboxes from one Exchange 2007 server to another server(new hardware, different server name, both on the same domain).
What steps do I need to take to ensure that no users access the mailbox stores during the migration process?
- Disable port 25?
- Disable OWA?
I will be using the move-mailbox exchange console functionality.
Fortunately this is not something you need to worry about. During the migration, there will be short periods where the mailbox is not available, but there is no chance for data loss.
Regardless, it's usually a good idea to schedule moves for low-usage times to minimize the user annoyance factor.
