I'm designing a migration from PST's to the Personal Archive on Exchange 2010. The current setup is using Exchange 2007 + Outlook 2007.
One of the possible migrations paths I'm thinking is to move all the PST from a single user to a new Exchange 2007 mailbox for that user. The idea is more or less that each user will have a personal mailbox and a shared mailbox for the archive (the only user accessing this shared mailbox is the owner of the data, of course). The end result is that the user has two mailboxes, the primary and the exclusive shared mailbox, both in Exchange 2007. The I will upgrade my server and client infrastructure to Exchange 2010 + Outlook 2010.
Next, I would like to move the data on the exclusive shared mailbox in Exchange 2007 to the true personal archive for that user.
Can I move data from a mailbox/shared mailbox to the personal archive of another mailbox? A workaround will be to move data from the shared mailbox to a temporary PST and then to the personal archive, but it would easier to move it directly.
