Starting with version 9.7, the vCloud Director appliance includes an embedded PostgreSQL database with a high availability function. You can migrate your existing earlier version of vCloud Director environment with an external PostgreSQL database to a vCloud Director environment that consists of vCloud Director 10.0 appliance deployments.

You can migrate a vCloud Director environment that consists of vCloud Director installations on Linux or vCloud Director appliance deployments. Starting with version 10.0, the Microsoft SQL database is no longer supported and you can migrate only a vCloud Director environment that uses an external PostgreSQL database.

If your vCloud Director environment uses an external Oracle database or an external Microsoft SQL database, you must migrate to a PostgreSQL database before upgrading to vCloud Director 10.0. For upgrade paths, see Upgrading vCloud Director.
