How do I perform a migration with two different types of licenses?
You can't perform a migration with two different types of licenses. You can only launch as many migrations as you have licenses for a specific type. You can see this if you go to your License Summary in MigrationWiz.
Note: If you purchased the User Migration Bundle license, then you can perform multiple migrations of various types. For example, you can perform a mailbox migration, and then later perform a document migration without having to purchase additional licenses. Refer to these articles for more information:
