Hi Mary!
As far I know, there isn’t a way to duplicate shipping zones with all his methods as once. (But maybe some plugin does it).
Fish and Ships includes an import/export tool. You’ll find the buttons inside every method, at the bottom. It can be used to duplicate methods and/or move configurations between stage/production sites (also to help us to debug)
For use it, enter to any FnS method, click export and copy all the given data. Then create a new empty method, enter on it, click import and paste.
This trick only works for Fish and Ships methods, of course.
Please, confirm if my reply are useful for you
Kind regards,
