I'm going to be doing an interesting (not really) Exchange migration for 50 users in the next month or two. The only reason it's quasi-interesting is because they are currently in a VDI environment managed by another MSP. Having a ton of Performance issues in their whole environment which includes EHR/PM software (SRS), Exchange (2010), some eRx and eFaxing, pretty vanilla environment. So here's my question that I think i've already answered. How would you migrate the users from exchange moving their PSTs to the new environment?
Assuming you're referring to Office 365 as the new destination, There's a few ways to go about it. You could hook up 365 to the existing Outlook installs as a second account, bring the PSTs into the archive mailbox for the new users, then later do a cutover migration. Alternatively, you could do the migration, then later import the PSTs into the archive mailboxes. On a less optimal note, if the archives are strictly time-based, depending on how your users manage mail, you could re-import the PSTs back into the main mailboxes, then do the migration (though this could lead to some sizeable mailboxes).
If the destination's an onsite Exchange server, you could just write a powershell script to batch export all mailboxes to PST, move them across, then batch import them.
