asterisk users - May 2018 - Big leap - 1.8 to 15.4.0

Hi all

We have to upgrade soon from prehistoric Asterisk 1.8.32.0 to Asterisk 15.x.x
(whatever minversion is current at the time.)

We are quite heavily invested into 1.8.32.0 at about 17 sites locally and
internationally and have a LOT of custom software running our sites via AMI from
various applications.

What are big gotchas to watch out for? Especially regarding PJSip as I've
been following posts and forums and it seems theres massive changes there,
nevermind just overall changes in jumping years of dev ahead on the Asterisk
version...

What should I watch out for so that our sites don't collapse completely on
telecoms functionality when we go to 15 from 1.8? Any resources I can refer to?
No upgrade guide I can find cover -this- wide a leap in versions.

I assume virtually every site's dialplan will have to be rewritten from
scratch, which in itself is already a massive undertaking.

Anybody with some advice?

Thanks,

Stefan

You more or less have to follow the guidelines as if you were doing one step at
a time (in terms of version) upgrades.

So you should consider the following documents in the source tree:

UPGRADE-10.txt
UPGRADE-11.txt
UPGRADE-12.txt
UPGRADE-13.txt
UPGRADE-14.txt
UPGRADE.txt (which would be 15)

Asterisk 15 still has chan_sip as well so I would give that a try before also
doing the switch to chan_pjsip. Otherwise your upgrade task will be a lot
bigger.
