Impact of changing name of an existing logic value

I never done this before but i am not sure if this works.

What happens if you have a (true/false) logic value and you use this in a lot of flows and you simply change/rename the name of the value…

Does this work or will it kill all flows where the value is used?

Where the logic value is used as a token, it will automatically change.
Where the logic value is typed in it will break the card, in 99% of the cases it is the card where you set the value
the app “Flow checker” will see all broken flow cards though, so highly recommend that app.
