It is not a seamless deploy but it worked for a one-shot transfer.

Here is what worked for me:

1. go to the original workflow and click "switch to code version (YAML)"
2. select all and copy
3. go to the new workspace and click create new job
4. click "switch to code version (YAML)" and click paste
5. in the new workspace go to the compute and select the compute you wish to use. Then clik on the View JSON and copy the compute ID
6. got back to the new job in the new workspace and paste this compute ID where ever you have "existing_cluster_id": XXXXXX (replace the XXX with the new id)
7. click save and view in visual mode
8. adjust as necessary
