I have been away for a week in New York again and just got back in the office and cleaned up a little of my emails. In parsing them, I wanted to pass along some information that on Side by Side assembly deployments with BizTalk and how to get this to work.

If you create another version of an already deployed Biztalk assmbly and you would like to start the new version, here is what you need to do to get this to work.

1. Configure any pipeline components to use a specific version of the schema. 
2. If the schema is redeployed under a different version and this is not done it will fail because it looks up by target name space / root element not by assembly.
3. Deploy the new version
4. Bind the orchestrations. 
5. The Manual steps are below
   1. Disable the receive location
   2. Unenlist the old version using the Explorer (do not stop it), this will prevent new instances from starting  while allowing old ones to finish
   3. Enlist the new version and start it, all new instances will be created using this one.
   4. Enable the receive location
