Backing up custom JRE certificates before upgrading Agent Manager

When upgrading external Agent Manager, if the new Agent Manager uses a higher version JRE than the old Agent Manager, the JRE TrustStore (caserts) in the old Agent Manager will be replaced by the new TrustStore from the higher version JRE. This will cause all the custom certificates imported to the old JRE TrustStore by customers get lost after the Agent Manager upgrade.

If yes, copy the file <fglam_home>/jre/<current_jre_version>/jre/lib/security/cacerts to a local directory before upgrading Agent Manager.

As for the embedded Agent Manager, it uses the same JRE as the Management Server. If there are custom JRE certificates stored in JRE TrustStore and a higher JRE version is used, back up the JRE cacert TrustStore used by the Management Server before upgrading Management Server.

Below is a list of JRE versions used by Agent Manager on various platforms in this release.
