Hi
You will need to reapply the RM AMP, as the RM extension modifies the web application (WAR). If there is an upgrade to the Alfresco WAR, then this still needs the RM mods adding to it.
Any of the effects on the repository of applying an AMP are not repeated if the AMP is reapplied to a later Alfresco WAR.
We're planning to create upgrade installers that can reapply any AMPs in the future.
Have you reapplied the RM AMP to the 2.0.1 WAR?
Cheers
Paul.
