The "APM Any Language" license only works from Controller version 4.3 onwards, so upgrade the Controller to 4.3+ before using this feature.
The APM Any Language license units allow a user to utilize a single entitlement for any of the major APM monitoring solutions, so it is possible to adjust the license units across the components.
1. Follow the below link and use the instructions found there to convert the old license to an APM Any Language license:

2. Once the license has been converted, verify that all agents are reporting correctly. If no agents are reporting, edit the license rule and ensure the license units are allocated properly.
