I can move the biggest databases easily with no failure or any warning between mysql to mysql or mysql to mariadb between localhost or remote host servers with a custom script of my own.
MariaDB 10.1.23 version on a directadmin setup server with phpmyadmin 4.7.2 full root access
We got pretty heavy network traffic for a single website in 2 months with 14.2tb
one of my biggest database is 1gb of data as we all know standart websites on market they got around 100mb
