Update from Asterisk Ver. --> Asterisk 12... Help needed please!

I have an old Asterisk 1.8 and I would like to update it to Asterisk 12.
A really nice guys, [TK]D-Fender, told me I shoudn’t restore a Asterisk 1.8 backup on an Asterisk 12 because it will not work really good.
He told me to update manually to the Asterisk12.

I updated the most packages and now, I would like to update my Distro from Asterisk Ver. to Asterisk 12.
How can I do it ?

Thanks you very much for your nice answer. :wink:
