I agree with Ashley 100% water changes generally won't affect your biological filter since most of the bacteria is in the filter media and the gravel.
That said though.....Puriti has an amazing amount of fish in her 10 gallon right now so I'm not sure that in her case she does have time for a "fishless" cycle.
Puriti when is the last time you changed the filter media on your 10 gallon? If it wasn't recently then I would go ahead and change it now and try to use some of the old filter media in the new 20 gallon to help jump start your cycle.
