A little while back, I upgraded some systems from Asterisk 1.4 (I
believe it was 1.4.29.1, and they were already running DAHDI), to 11.
11 made the most sense as far as it being a LTS release so it would be
longer before being forced into a new version (as far as continued bug
fixes and things), and I figured it would be more stable than 12.
The upgrade wasn't too difficult, even jumping several versions. I
*strongly* suggest reading the various "UPGRADE-XX" files that come with
the Asterisk source so you don't get caught by any changes between
versions. There are quite a few changes and each dialplan is different,
so things that caught me would be different than what you might run
into. Those upgrade text files are extremely useful in this case.
Beyond that, I spent a lot of time migrating my config files. Since
newer versions have newer / different options, I didn't just keep my old
files. For example, for SIP.CONF, I went through and modified the
default settings in the new file to match what I needed, copied over my
site-specific sip definitions from the old file, then double-checked
everything. I did that with each file that I had modified (and in your
case, you'll have to go from zapata.conf to chan_dahdi.conf). It can be
tedious, but it really only took me a day or two (taking time to
double-check my changes). Overall, not a bad experience at all.
Awesome to hear that! Backwards compatibility is certainly at our
forefront these days when doing development and we try our hardest to
make the experience of upgrading as painless as possible from that
perspective.
Cheers,
