Why Data in MariaDB and SysDB Cannot Be Migrated or Synchronized?
Context
In some MariaDB versions, the SysDB database is used as a system database (similar to the sys database of MySQL 5.7). Therefore, DRS considers the SysDB database as the system database of all MariaDB databases by default (similar to the MySQL, information_schema, and performance_schema databases).
Solution
If the SysDB database is a service database, submit a service ticket.
