A trial licence is fine for testing some stuff, but if you need to remove it, for example when it causes you issues in a stack when the master thinks it on perimeter, but the backup is not.

Here is an example, Slot 1 in this case had “Advanced Edge” we needed that to be removed. To do this perform the following steps:
Slot-1 switchstack1.26 # clear license-info
Are you sure you want to clear license information stored in EEPROM? (y/N) Yes
A reboot is required before the clear license takes effect.
