Backing up the administration database

Backing up the project administration database (talend_administrator) is mandatory before starting the migration process.

Before backing up the project administration database, pause all currently active tasks in Talend Administration Center.

If you migrate from database X to database X (ex: from MySQL to MySQL), the database backup is performed directly in the web application in the first step of the migration process.

If you migrate from database X to database Y (ex: from H2 to MySQL), you need to back up the administration database manually.
