Migrating Exchange From 2003 to 2013 via 2010
Hi, apologies for the rookie question, but we are looking to migrate our mail system from MS Exchane 2003 to eventually 2013 with Exchange 2010 as the interim step, ie. no user will be using this ver...
I thought you said no mailboxes were going to be using Exchange 2010? If no mailboxes will be archived from 2010, there is no reason to target it in EV. In that case, the vault service account would live on 2013. The Exchange 2003 environment should still work. Just make sure you dont move the Enterprise Vault system mailbox from 2003. The old 2003 tasks need to still point to a system mailbox on 2003. You'll need new system mailboxes for 2013 tasks (see the Installing and configuring guide pg. 62 for guidlines if using a DAG).
