Upgrades between minor versions of the agent, like from 1.1 to 1.2 are always backwards compatible. Upgrades that involve a major version bump often come with some backwards incompatible changes.
Before upgrading the agent, be sure to review the:
-
{apm-guide-ref}/agent-server-compatibility.html[Agent and Server compatibility chart]
-
Shut down the application.
-
Download the latest release of the agent jar file from maven central.
-
Optionally change JVM settings, e.g., if the path to the agent jar has changed due to a different file name.
-
Restart the application.
We love all our products, but sometimes we must say goodbye to a release so that we can continue moving forward on future development and innovation. Our End of life policy defines how long a given release is considered supported, as well as how long a release is considered still in active development or maintenance.
