Yes.

They belong on the existing question - unless the existing question is poorly asked and the new one is better asked.

New answers can, by default, be added at any time - and should, if existing answers are actually out of date rather than simply being old. (Many 10+ year old answers really do still apply.)

Asking the question again is not how the site is designed or intended to work.
