Move archive along with mailbox migration
I looking for suggestion/recommendation and best practices for the below scenario
Here is the existing setup,
Destination Exchange server: Linked mailboxes in Exchange 2010 in the resource forest
Source Exchange server: Exchange 2003 Sp2
Source Archival: EV 7.0, Existing Site
Destionation Archival: EV 9.0.1, New Site
As part of exchange mailbox migration I would be moving the mailbox from Exchange 2003 to 2010. Here I have question, Exchange 2003 mailboxes are already archival enabled , so when I move the mailbox to 2010 what happens to the archived data?
Will the user be able to access the archived data post mailbox migration?
Are there any best practice to follow in these situation where mailbox & archived data are getting moved to New Exchange 2010 & EV 9.0.1?
