I have freepbx 12 installed with asterisk 13 and centos 7 and database server is mariadb but i want to uninstall the mariadb server and install the mysql server.
I have concern If I do that my freepbx database will crash or my tables will crash.
please guide me with proper steps I am really very thankful to you.
Literally there is no difference between MariaDB and MySql. There might be a problem somewhere else and most probably moving back to MySql will not solve your issue too.
