Hi Robert.

Can you utilise the Merge command to transfer the old global data to the new?

Does the EnsLib.HL7.Adapter.TCPOutboundAdapter class exist in your namespace? (It should being a library class)
If it doesn't I would recommend finding out how that could have happened.

If it does make sure the class is compiled as Muhammad has suggested. The other thing to check would be the mappings.
