Attempting to Migrate TFS2012 project from one server to another using TFS Integration Platform

Question

I have migrated all of the Version Control items with no issue. The Work Items are a different story. I always end up with a SoapException: SourceAreaId. Both projects use the same Process Template. I've used IntegrationPlatformMappingTool.exe to create the FieldMappings. I know there is one other person who has experienced this issue, but there was no resolution. They reported the issue on CodePlex and MSDN

I'm not really sure what else to try. Any thoughts?
