how to integrate databases?

hello everyone.

we have several mysql DB. And we have the plan that integrates each DB with mariadb galera.
And we will integrate db one at a time.

But I don’t know that how to integrate db using XtraBackup in progressively.
I have used XtraBackup at a single instance(database).

only method is mysqldump?


what storage engine you are using for all those databases? and in which MariaDB galera version you want integrate those all?
If its innodb and you are using InnoDB_file_per_table then with 5.6, you can also import individual tables.
