title: box API 1 token and box AP1 2 tokens
body: <p>I have a system the currently integrates with box using API 1.0.  My existing user have tokens that were issued by API 1.0 thus these tokens do not expire.  I see that API 1.0 is being deprecated in Dec.  Reviewing API 2.0 access tokens expire in 1 hour.</p>
  
  <p>The question I have is that when I make the switch to API 2.0 will all my existing users have to get new access tokens.  If no, will the API 1.0 generated tokens never expire?</p>
