Switching to synthetic oil

I've read about how much better synthetic oil is and how much cooler my bike could run on it. Now, can someone tell me how how important it is to get all of the conventional oil out before putting the synthetic in. I assume the two oils mix well enough that it doesn't matter if I don't get it all out. Is this true?
