Changing to a longer circular needle

I am a beginner knitter and am making a poncho on a circular needle. The stitches are getting crowded and I would like to change to a longer needle without taking all the stitches off the needle. How do I knit the current stitches off on a longer needle. I know how to do this with straight needles, but I can’t figure how to do it with a circular. Please help me. Thanks
