How can I safely experiment with reordering my feeds yet be able to return to the original order?

My feeds are in a “special” order - I organized them back when Newsblur allowed arbitrary (re)ordering via drag and drop. I don’t want to lose that order but I would like to experiment with putting some of my top feeds into folders and be able to save or revert to my original ordering. Can I do that with and be assured that it won’t affect the production site? Would exporting my feeds allow me to import them and restore to my preferred order? Or is this just not possible?

I don’t know whether this is possible at all, but using the beta site won’t help you as it shares data with the main instance.
