Prepare to upgrade your Java Agent

 

Plan your Java Agent upgrade

  • To ensure a successful correlation, upgrade agents on downstream tiers first, and then on upstream tiers.

  • If you’re upgrading multiple agents in your monitored environment, upgrade the agents for the tiers on which business transactions are originated last.

  • Starting in release 4.5, Java Agents are automatically backward-compatible with any 4.4.1+ Controller, so you can upgrade your agent while retaining your 4.4.1+ Controller.

    Note: If your Controller is older than 4.4.1, you must upgrade your Controller before upgrading your Java Agent.

    Supported
    Controller
    Versions
    v4.3 v4.4 v4.5 v20.3 - future releases
    Java 4.x - 4.3 4.4.1 - 20.x (1) 4.5 - 20.x (1) 4.4 - 20.x (1)(2)

(1) Controller version supports through the most recent released Agent version

(2) Controller version does not support Agent version 4.1

 

 

Shut down the JVM when uninstalling Java Agents

When uninstalling, it’s important to shut down the JVM that the Java Agent runs on, or the Java Agent will reappear in the UI. See Uninstall the Java Agent for the correct procedure.
