Freepbx upgrader GUI

Discription : This module allows FreePBX 2.11 to be upgraded to FreePBX 12, the next major version.
cat /etc/asterisk/freepbxdistro-version
my question is can I use Freepbx upgrader GUI to upgrade to Freepbx version 12 or should I follow the link

You need to upgrade your Distro which will handle the FreePBX GUI upgrade also for you by following that link.

I think I will do clean install with asterisk 11
