Depending on where you live, and what your zone is, will be the deciding factor on when to divide. If you are in a warmer area, dividing now would be just fine. You just need to make sure that each division has some roots. If it is already freezing at night, I'd wait until Spring.
Daylilies can live a really long time! Can't see having to ever replace them, if they are growing well and are healthy!
