Switching to Another License
FlexNet Manager Suite 2019 R2 (On-Premises Edition)   
    In a simulation, the link between an application and its license is fixed. Therefore, if you
      want to experiment with the costs of switching to a different license for a particular
      application, you must:
    - On the particular computer, delete the application record (this also removes its license).
 - Create another copy of the same application on the same computer, and in the creation process, specify the alternative license.
 
Tip: You'll be able to quickly revert both changes if you want to switch back to the
      original license.
