Feature key

I have an old canopy sm lite I just want to change it to canopy ap. I read in an article here in cambiumnetworks
that i can change it through feature keys my esn on canopy hardware is 0a003edb2848 and in sofware is 0a003efe4e23. can anyone else can help me on giving me the feature key.

You cannot convert a PMP100 Canopy Lite SM to an AP.

In addition, PMP100 series is end of life so you will no be able to get support or feature keys for this series.

I'd suggest that you go on eBay and buy a used PMP100 AP.
