Just transfer the frames from the old box to the new one. Would it be the first time the frames have been removed? going by your question. If so it would be a good opportunity to scrape everything clean again. Mainly propolis & burr comb, also check to see if the QX has any cracks in it.
Have a paint scraper handy and lever the frames out of the old box gently. Use the paint scraper as a knife to cut the bur comb between the frames. Take your time and it will go ok. If the frames don’t want to budge it might be easier done with the old super of the hive and cutting away any burr comb from the bottom of the box.

Welcome to the forum Randy. I would email Flow and ask the price of the super box in the wood of your choice. They can supply it but it isn’t listed in their catalogue.
Cheers
