Administrators can use the Directory Proxy Server’s update utility to update the current server code with the latest features and bug fixes.
Ping Identity issues new software builds periodically and distributes the software package in .zip format. To update the Directory Proxy Server to a newer version, download the build package, and then extract the new server package on the same host as the server you want to update.
Before upgrading a server, ensure that it is capable of starting without severe or fatal errors. For more information, see Planning your upgrade.
During the update process, the updater checks a manifest file that contains a MD5 checksum of each file in its original state when installed from .zip. Next, it compares the checksum of the new server files to that of the old server. Any files that have different checksums are updated. For files that predates the manifest file generation, the file is backed up and replaced. The updater also logs all file changes in the history directory to tell what files have been changed.
For schema updates, the update tool preserves any custom schema
definitions (99-user.ldif). For any default schema element changes (if
any), the updater warns the user about this condition and then creates a patch schema file
and copies it into the server’s schema directory. For configuration files, the
update tool preserves the configuration file,
config.ldif, unless you need to add new configuration options to
the Directory Proxy Server.
When the updater finishes processing, it checks if the newly updated server starts without any fatal errors. If an error occurs during the update process, the update tool reverts the server root instance to the server state prior to the update.
