"Workflow Activities with GUID characteristics found in source XOML" error message (4314611)

When migrating a site or site collection, log entries similar to the one below are encountered:

The warning message means that there are activities in the XOML mapping that have not been explicitly mapped. Content Matrix will detect activities that are not mapped, which could cause potential issues.

There is a WorkflowConfiguration.xml file in C:\ProgramData\Metalogix\Metalogix.SharePoint.Workflow, which contains the mappings. It can be modified so the activities that Content Matrix is warning about are added to the respective XML <WorkflowActivityCollection><Activities> element:

<WorkflowActivity Name="FindActivity" ActivityType="Nintex"> 
 <Attributes> 
 <WorkflowActivityAttribute Name="ListId" Operation="Guid" /> 
 <WorkflowActivityAttribute Name="ExternalListId" Operation="Guid" /> 
 </Attributes> 
</WorkflowActivity>

Note: The ActivityType will either be "SharePoint" or "Nintex" depending on its workflow type.

This is a sample WorkflowConfiguration.xml file containing the additional XML element as described above.
