To upgrade ActiveMQ, simply reinstall it to a new directory. The steps to do this are:

  1. Download the latest supported version of ActiveMQ. See Software packages and download locations for the exact version and location.
  2. Stop the ActiveMQ service.
  3. In case of Windows, uninstall the old ActiveMQ Windows service by running $activemq\bin\win64\UnInstallService.bat from an elevated command prompt.
  4. Follow the installation instructions from Installing ActiveMQ (Microsoft Windows) and Configuring ActiveMQ. It is possible to copy the keystore files, wrapper.conf, activemq.xml and from the old ActiveMQ service.
  5. Start the new ActiveMQ service.
  6. Remove the old ActiveMQ directory if the new one works successfully.
