Migration Wizard Question
I'm using the migration wizard to move our Exchange 2003 users to Zimbra 7.1.2. Our external gateway uses sendmail which then routes all mail to the Exchange servers.
My question is this. Do I need to shut down the sendmail gateway (and let mail queue up externally) while I'm running the migrations. Or is the wizard smart enough to know that new mail has arrived during the migration of large mailboxes and sync up at the end?
I want to avoid situations where mail is received at Exchange while I'm in the process of migrating and that mail isn't migrated to Zimbra.
