Anxious To Go Kindergarten That'll Take Up Current Naptime

My almost 3yo still takes his afternoon nap at 1+ till 3 or 4+. He will be going to kindergarten nxt year at 12-5. That'll mean that it'll be during his nap time. Do kids adapt easily? I read about how naps are still impt at this age. Anyone has experience and could you share how you adjust your LO's daily routine?
