How can I marge submissions from one form to another?

We have two identical forms (unsure how they were created) and would like to have only one active going forward.  Is there a way to merge the submissions since the forms are identical?  If not, is disabling one form the best way to proceed to ensure all submissions end up under a single form?

Thank you!
