☛ 1. Before jumping in to do as the error message suggests, let’s think for a moment about what that requires

☛ 2. Inspect every Receive and Send shape to determine if it uses a Message variable that’s associated with the schema you want to change.

☛ 3. It’s not a good practice to create a single orchestration with so many Receive/Send shapes

☛ 4. Delete Port connection, once you find all the Receive Send Shapes.

☛ 5. Change the message variable so that the message type property is set to the new schema and then re-associate the message variable with each Receive/Send shape.

☛ 6. Find all the port Types that are associated with ports you disconnected from Receive/ Send shapes and reset their operation’s message Type Properties.

☛ 7. Use a Multi-Part Message Type to wrap the underlying schema. It’s flexible and saves time in the long run.
