On Linux servers, use the Upgrade Utility to upgrade to the current version of PingFederate.
Upgrade results are contained in the upgrade.log file, which is located in <pf_install_target>/pingfederate/upgrade/log.
If you are upgrading to PingFederate 10.0.1 and you are using AWS CloudHSM, you must update your CloudHSM client and CloudHSM Software Library for Java to version 3.0. See the instructions in step 5 for more information.
End users might experience service disruptions as you upgrade your PingFederate environment. All nodes in a clustered environment must have the same major.minor version of PingFederate. So when you upgrade nodes in a cluster to another major.minor version, you must stop all the nodes before you upgrade any of them.
