Upgrading asterisk

I am sorry. I searched and got no results and nobody really knows how to do it right on the trixbox forums. (I use trixbox and I am very active on their forum)

So I need to “untrix” some boxes.
Is there a way to:
a) Upgrade asterisk 1.4.x to a higher level of 1.4.x?
b) upgrade asterisk 1.2 to 1.4?
c) upgrade asterisk 1.x to 1.6 and then 1.6 to future beta versions?

I know it sounds like a lot of work but I hope this would be simple as just sending me direct links
I would appreciate any help. Thanks a lot



Its as simple as reading the upgrade notes that are in each load of asterisk.

You will find it lists all the changes and what has replaced them.

Expect to do a lot of work.
