It's somewhat a matter of taste as there is no one right answer.
Either way, you need to redistribute your key (usually just reupload
to a keyserver).

I'd make the new subkeys, personally, but then I tend to like a longer
expiration time than 2 years.  If you make new keys every 2 years,
your key will eventually get pretty big.
