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:
Create a new Logic App (will open in new designer)
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):
Save your Logic App
Open your logic app in code view
Change the $schema value at the top from:
“$schema”: “http://schema.management.azure.com/providers/Microsoft.Logic/schemas/2014-12-01-preview/workflowdefinition.json#“, (I’ve
highlighted the bits that change)
Close your logic app
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.
