For major upgrades to the vCenter Server Appliance, you can deploy a new version of the appliance and import the network identity of your existing vCenter Server Appliance.

For minor updates to the vCenter Server Appliance, see Update the VMware vCenter Server Appliance from a VMware.com Repository, Update the VMware vCenter Server Appliance from a Zipped Update Bundle, and Update the VMware vCenter Server Appliance from the CD-ROM Drive.

Note

Version 5.0.1 of the vCenter Server Appliance uses PostgreSQL for the embedded database instead of IBM DB2, which was used in vCenter Server Appliance 5.0. If you use the embedded database with the vCenter Server Appliance, when you upgrade from version 5.0 to version 5.0.1, the embedded IBM DB2 database is migrated to a PostgreSQL database. The configuration state of your existing database is preserved and the schema is upgraded to be compatible with vCenter Server Appliance 5.0.1.
