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.

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?
