Be careful when starting the migration process right after the activation as the migration job that you set up in the trial version will still be present on the Jobs tab in the Administration Panel. If you instantly click Rescan, the previously migrated source mailboxes will be counted by the licensing program and will take licenses from the available pool.

Before starting or restarting the migration, make sure that the configured pairs of mailboxes / public folders are the ones that you want to migrate. If not, remove them by selecting a particular mailbox and choosing Unmatch target mailbox.
