ASA mode converted to NGFW

[Translator]

With an existing FPR2110, using ASA mode, containing 1,500 SSL VPN licenses, now I want to enable a Layer 7 license TMC, would anyone please let me know whether it's needed to migrate FPR2110SSL VPN and how?

The SSL VPN licenses (also known as AnyConnect licenses) are completely separate from the TMC (Threat, Malware and URL Filtering licenses). Each is enabled separately and does not affect the other one.
