Step by step upgrade from 13 to 14.4 please for RPi

I have a self-compiled Asterisk v13.5 install running on a RPi and it is doing quite nicely for testing for a client. I’d like to upgrade to v14.4 by recompiling from source BUT I don’t want the problems of redoing the config files. Is there a step-by-step guide for Asterisk dummies to run the 13 to 14 upgrade that keeps the same configs, etc?
Any links?

Unless you execute the “make samples” command then your config files won’t be touched. As well the UPGRADE.txt document contains things of note when upgrading.

Thanks, got the upgrade done painlessly.

Would you mind posting the exact steps you took to upgrade your self complied existing Asterisk 13 to 14
