In this release, users still have the option of migrating from an XML database to a relational database. Existing users who chose to take advantage of this possibility will need to explicitly redeploy their projects and migrate important system containers in order to do so. See the Talend Migration Guide for more details.

In particular, make sure you process the ACTIVE and FAILED queue before performing any migration, since the migration procedure will cause ACTIVE, FAILED and COMPLETED queues to be lost.
