I have four forms that I can merge into one. Basically, there are 4 personnel forms that can be combined into 1 that has a field differentiating them.
If we have previously distributed the form-specific URL (ie has the "...?ticket_form_id=15000000XXXXX" parameter), and we deactivate the 4 original forms, I expect that the user will end up at the page as if it had no parameter (rather than a 404). Is that correct?
Is there a way to redirect from one form-specific URL to another ((ie from "...?ticket_form_id=15000000XXXXX" to "...?ticket_form_id=15000000YYYYY")?
The way we support this type of setup is through host mapping, which requires a few other steps in addition to set the DNS. You can find more information in the article below

I hope this helps!
