Switching to the old Logic Apps designer from a new Logic App is relatively easy… if you don’t have anything in your logic app! You just need to change the $schema value at the top of your logic app definition.

Here’s an example of how to do it:

  1. Create a new Logic App (will open in new designer)
  2. Add a manual HTTP Trigger, and a delay action (you need at least one trigger and one action in order to save your Logic App):

  3. Save your Logic App
  4. Open your logic app in code view
  5. Change the $schema value at the top from:
    “$schema”: “”,
    “$schema”: ““, (I’ve highlighted the bits that change)
  6. Close your logic app
  7. Reopen it – it will open in the old designer (although it will appear to have nothing in it, as the new manual HTTP trigger is not supported) – just add a new trigger and off you go.
    Note: you may need to manually edit the code behind to remove the delay shape – your mileage may vary.

I suspect the product group will release a tool to make this easier.

You can also use this mechanism to go from the old designer to the new one.
