To move SQL Server databases used by vCenter Server to a new location:
- Stop the VMware VirtualCenter Server, VMware VirtualCenter Management Webservices and VMware Update Manager services.
- Migrate the VCDB and UMDB from the existing SQL instance to the new SQL instance running on the remote server.
- If migrating a vCenter Server 4.x local database, you may also need to migrate the ADAM database.
- Note the credentials and server that vCenter Server uses to connect to the database. Update the DSN as necessary to the migrated database.
- Recreate SQL Agent rollup jobs. Detaching, attaching, importing, and restoring a database to a newer version of SQL Server does not automatically recreate these jobs
6. Start the VMware VirtualCenter Server and VMware Update Manager services.
it may necessary to update the vcdb.properties file with the new SQL server if the SQL database name is referenced here. If this is not updated, the performance overview charts and the Storage Monitoring Service (SMS) may be affected after migrating the vCenter Server database
