Introduction to Upgrading Directory Proxy Server

When upgrading Release 4 Directory Proxy Server to Release 5, consider the following aspects of the upgrade process:

• General Upgrade Approach. The upgrade is achieved by performing a fresh install of Release 5 Directory Proxy Server and then configuring new Directory Proxy Server instances using the Directory Service Control Center or Directory Server EE command-line utilities.

• Upgrade Dependencies. Directory Proxy Server has dependencies on a number of Java ES shared components, see Table 1–7, all of which are automatically upgraded to Release 5 by the Java ES installer when you perform an upgrade of Directory Proxy Server.

• Backward Compatibility. Release 5 Directory Proxy Server can be configured to be backwardly compatible with Release 4.

• Upgrade Rollback. A rollback of the Release 5 upgrade is achieved by reverting to the previous version, which is left intact by the upgrade to Release 5.
