Do you need to restore MySQL database after upgrading to MariaDB?
There is no need to dump and restore databases. As with any upgrade, we recommend making a backup of your data beforehand. You should run mysql_upgrade (just as you would with MySQL) to finish the upgrade. This is needed to ensure that your mysql privilege and event tables are updated with the new fields MariaDB uses.
Do you need MySQL 8.0 replicas to upgrade?
The replicas recognize the old format and handle it properly. Binary logs created by the source subsequent to the upgrade are in 8.0 format. These too are recognized by the 8.0 replicas. In other words, when upgrading to MySQL 8.0, the replicas must be MySQL 8.0 before you can upgrade the source to 8.0.

Can a MariaDB table be imported into another DBMS?
