If you want to get up-to-date answers for an old question, you can place a bounty on that question.
See: How does the bounty system work?
You can enter a message asking users to provide new answers with current information. The question will then appear in the "Featured" tab on the main site and is likely to be seen by more users.
This is especially useful if the old question isn't sufficiently answered — although in this case it appears to be, so you might want to explain why you'd need to get more answers or what information the current answers are lacking.
