Note: If you've configured HA for your PAM360 instance, your secondary application server should always run the same version as your primary server. For instance, if you're upgrading to 5000, you should concurrently reconfigure HA and set up a fresh secondary instance that runs 5000. Additionally, ensure that the software architectures are also the same.
