We have a system built using AsteriskNOW that currently stands at the following versions:
We haven’t upgraded it (as you can see) purely because it has a very complex call flow and dial plan and we have not wanted to risk hosing the box.
My question is, if we take a backup of the system, what version of Asterisk+FreePBX can it be restored to? Can it be restored to a FreePBX Distro install or does it have to be an AsteriskNOW install? If it can be restored without issue to a FreePBX Distro, what version would it be safe to do so with?
