We have Boolean fields with the values Yes/No which are widely used within our instance and workspaces. This field should not be used in any forms and is not connected to our CRM in any way. If we were to change this to a picklist (With three values of Yes/No/Unsub), is there a good understanding of what will occur? For instance:
1) Will leads hold their current value of Yes or No?
2) Will leads have their current value reset?
Any insights would be very much appreciated.
