Oracle VM Release 3.0 is not backwardly compatible with previous Oracle VM releases. If you are using Oracle VM Release 2.x you cannot upgrade to Release 3.0.3. You must reinstall your Oracle VM Servers and Oracle VM Manager. You can, however, reuse your virtual machine templates from Oracle VM Release 2.x by importing them into Oracle VM 3.0.

The upgrade procedures discussed in this chapter refer to upgrades between Oracle VM 3.x releases, for example, upgrading from Oracle VM Release 3.0.1 to 3.0.2. This chapter outlines the upgrade process for all the components of Oracle VM when upgrading to minimize down time and make sure the upgrade process is performed in the correct order.
