We have an FMC VM and an ASA 5516-x with Firepower services. We have been using classic licenses until now. However, that version of the license is reaching the end of support. Therefore, we need to purchase new replacement model SKUs that require a Smart Account. After assigning the licenses to the Smart Account, I registered the FMC using the Smart Account, but the licenses are not appearing in the FMC's Smart Licenses session. I assumed this happened because of Classic licenses are still being used by the FMC. I want to know if there is any way to remove these classic licenses and start using the Smart Licenses.
