To make sure you complete all the tasks necessary for upgrading your dynamic language agents after a release, we recommend following the instructions in our upgrade checklist. This guide is not release-specific and can be referenced for any release.
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. If your Controller is older than 4.4.1, you must upgrade your Controller before upgrading your Language Agent. Review the Agent/Controller compatibility matrix for compatibility mappings between Language Agent and Controller versions.
Tip! Upgrade agents first on downstream tiers and then on upstream tiers to ensure a successful correlation.
Tip! If you are upgrading multiple agents in your monitored environment, upgrade the agents for the tiers on which business transactions originate last.
