The Governance Services AMP files can be uninstalled using the Module Management Tool (MMT).
Governance Services consists of two AMP files, which are applied during installation. One of the AMP files, representing the core Governance Services functionality, is applied to the Alfresco Repository WAR file, and the other, representing the Governance Services UI component is applied to the Alfresco Share WAR file.
Both of the AMP files need to be removed in order to uninstall Governance Services. Use the Module Management Tool (MMT) to do this. For more information on the tool, look for the Module Management Tool (MMT) in the Alfresco Content Services documentation.
The MMT is a command line tool. The syntax for uninstalling an AMP file using MMT is:
$ java -jar bin\alfresco-mmt.jar uninstall <ModuleId> <WARFileLocation>
