Starting with version 9.7, the vCloud Director appliance includes an embedded PostgreSQL database with a high availability function. You can migrate your existing vCloud Director environment of an earlier version to a vCloud Director environment that consists of vCloud Director 9.7 appliance deployments.

You can migrate a vCloud Director environment that consists of vCloud Director installations on Linux or vCloud Director appliance deployments. You can migrate a vCloud Director environment that uses an external Microsoft SQL database or an external PostgreSQL database.

If your vCloud Director environment uses an external Oracle database, before migrating to vCloud Director appliance, you must migrate the database to PostgreSQL from vCloud Director version 9.1. For information about the workflow for upgrading a vCloud Director installation with an Oracle Database, see Upgrading vCloud Director.
