Prepare to upgrade your dynamic language agent


Plan your dynamic language agent upgrade

  • Starting in release 4.5, Language Agents are automatically backward-compatible with any 4.4.1+  Controller, so you can upgrade your agent while retaining your 4.4.1+ Controller. See Agent and Controller Compatibility documentation.

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

  • To ensure a successful correlation, upgrade order should begin with agents on downstream tiers, followed by those on upstream tiers.

  • If you are upgrading multiple agents in your monitored environment, be sure to upgrade last the agents for tiers on which business transactions originate.

    See the following documents for step-by-step instructions, as needed:



In the event of a failure, uninstall the newer agent version and reinstall the previous version. Once it has been reinstalled, restart the application.
