How do I know which users have consumed a license in Notes Migrator
You can tell who was migrated by looking at the Status column. A Status of "Migrated Successfully" means a user was migrated and a license was consumed.
A license is consumed per user, not per migration event. This means a single user can be migrated multiple times, yet only consumes a single license.
The caveat to this condition is if you removed the user's back-end SQL record from the 'CMT_Users' table. The license is stored in this record. If the record is removed, then an additional license will be consumed if the user is selected for another migration event.
Example: 100 licenses have been applied, and you have 10 users migrated. This leaves you with 90 licenses remaining. As long as you did not remove the back-end record, you can migrate all 100 users without requiring additional licenses.
