So we have successfully moved all mailboxes from 2k7 to 2k13 and I've updated all DLs using the set-distributiongroup -forceupdate command. Before we start migrating public folders, what else needs to be done to upgrade other exchange objects? For instance if I look at a mailuser object, its exchange version is still 2k7. Do I need to do anything to upgrade those objects? Also, things that carried over from 2k7 such as my email address policy, will those stick around once I decommission
2k7 environment? Thanks!
