So I've been running build 90 for several test users and want to upgrade to build 104. Since I'm running a VM, my plan is to revert the snapshot and re-install the new version from scratch.

My question is what is the best way to handle the re-sync of data to the phones. Should users just delete the accounts on their phones and re-create after the install is complete? Or if left in place, will the phone accounts just pick up where they left off once the new server side software is installed?
