Automatically fill new field for previous data type

Hello I’m facing a issue here related to new fields and data types:

I have a version live, everything is working fine. But now I want to add a new workflow for which I need a boolean in my Users (default yes). I create this new data field and check in the workflow if the boolean is yes/no in order to do some stuff.

EXAMPLE: if new boolean = yes → print (“YES”)
if new boolean = no → print (“NO”)

PROBLEM: when I deploy this new version, all my current users have this new boolean empty (nor yes neither no), so my workflow does not work. I can MANUALLY change all users from database but that is a nightmare. Is there any way of automatically make all previous users to set this new boolean to the default value?

Recursive API Workflows is what you are looking for.
