Prepare to upgrade your Machine Agents

  1. Review the Product Announcements and Alerts page for details on any intermediate versions between the current version of your instance and the version you are targeting.

  2. Review either of the following to confirm the compatibility of the various components of the AppDynamics environment:

 

Plan your Machine Agent upgrade 

  1. Review the Machine Agent and Controller version compatibility information below:

    Supported
    Controller Versions
    v4.3 v4.4 - 4.4.3 v4.5+ v20.3 - future release
    Machine Agent Versions 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 does not support Agent version 4.1

  2. Review the list of Machine Agent supported environments and versions to ensure compatibility between your Machine Agents and JDK.

    For example,
    4.0.x is the latest version that can run on JDK 1.5 and higher, and any version from 4.1.x and higher needs JDK 1.7 or higher.

  3. See Upgrading the Machine Agent for step-by-step instructions.

Note: It’s a good practice to back up the <machine_agent_home> directory to a <machine_agent_home_BACKUP> in case you need to revert to the previous installation.

 

Troubleshooting

In the event of an error condition, uninstall the new version and reinstall the previous version of the Machine Agent.
