Changing Lookup field to point to moved form

Changing Lookup field to point to moved form

When I originally set up the application, we were prototyping multiple different approaches. To avoid having to set up the same config again and again, I put the config into a separate app.

We have now decided on the approach we want to use and I am moving the config into that app. How do I update the lookup fields in the chosen app without needing to disable [comment out] all the references to those fields in workflows?
