If they have both been running continuously for a month you should be fine, assuming everything else is okay, you've been using appropriate water conditioners, etc.

Better safe than sorry, when you remove the old filter, test daily for ammonia, nitrites, and nitrates, and be ready with large water changes if there is a "mini-cycle".
