How to update an asterisk built from source?

Question

linux

Good afternoon.
There is an asterisk built from source:

[[email protected] ~]# ll /usr/src/
drwxr-xr-x 28 1013 users 4096 Apr 13 22:45 asterisk-11.25.1
-rw-r--r-- 1 root root 35125897 Dec 9 03 :11 asterisk-11-current.tar.gz
drwxr-xr-x 4 root root 74 Mar 2 2016 dahdi-linux-complete-2.11.1+2.11.1
-rw-r--r-- 1 root root 8517162 Mar 2 2016 dahdi-linux-complete-current.tar.gz
drwxr-xr-x 4 1013 users 4096 Feb 27 14:00 libpri-1.5.0
-rw-r--r-- 1 root root 340683 Mar 28 2016 libpri- 1.5.0.tar.gz

What if I want to upgrade to version 13?
Is it enough to download the sources and compile version 13 already?
And the situation is also reversed if, for example, there is a 13th version compiled from sources (without PJSIP), but it is necessary to roll back to the 11th. What steps to take?

Answer 1

Yes, in general, everything is like this - make a backup copy of the configuration and the contents of /var/lib/asterisk (it will be stung during cleaning), delete, clean out the old Asterisk, install a new one, deploy backups and check that all old configs still work. It's a good idea to review the version differences to be aware of which configuration settings have been changed.
