Upgrade frrom Asterisk Asterisk 15.4.1 to FreePBX

Hi Team,

I would like to know how to upgrade from Asterisk 15.4.1 to FreePBX.

Please advise.

Thanks

Asterisk VOIP framework, FreePBX it is a GUI who provide easy configuration of some PBX features using the Asterisk framework, so I think you are a little bit confused, you can upgrade from Asterisk 15 X to Asterisk 16 ,but FreePBX upgrade it is totally different process
