More specifically, take the "patches" folder and copy it over to your other wow folders, then run each wow individually and let it update. This just preserves the individual settings and addons you might have set up within each folder.
What patch folder? Are you referring to the "Patch.MPQ" file inside your data folder? ... That's the only thing I can think of referring to patches
