I would have thought that:
UPDATE x SET y = DATE_ADD(y, INTERVAL 2 DAY)
But that is adding two days, the original query was to add two months, so presumably
it should be "INTERVAL 2 MONTH" - but beware that MySQL does some
seriously bizarre things with dates - for example adding 2 months to 31st Dec
takes you to 31st Feb which probably isn't what you want.
would work and not alter the time, but only a test will tell.
