Good things rarely come from making radical changes at the last minute. If you see any failures in the days after upgrading you have a new variable to consider on the cause. Look at what the best/worst outcomes are from making the change - does the risk justify the benefit? Would I do it? yes probably, I can't sleep if I'm on a 3 when I know there is a 4 around.
