8. Upgrading Oracle VM

Oracle VM Release 3.x is not backwardly compatible with previous Oracle VM releases. If you are using Oracle VM Release 2.x you cannot upgrade to Release 3.1.1. You must reinstall your Oracle VM Servers and Oracle VM Manager. You can however upgrade between Oracle VM 3.x releases, for example, upgrading from Oracle VM Release 3.0.3 to 3.1.1. See the Oracle VM Installation and Upgrade Guide for information on upgrading between Oracle VM 3.x releases.
