Need instructions to migrate APM Management Modules.
APM On Prem 10.8
Documentation
Basically , For upgrade/migrate of management modules..
1. Stop the EM.
2. Place the management modules JAR files under /config/modules
3. Start the EM.
If an older version MM is detected by an EM it will automatically update the MM as it loads it for the first time, to the latest MM format. This is done automatically upon loading the MM, no manual process is needed to upgrade MMs from older versions of APM.
If you use hot deployment or specific domains for the Management modules , please refer the guide:
Also, in a APM cluster environment, make sure the 'domains.xml' on the Collectors and MOM are the exact same with proper file/folder permission.
