I currently hold a ESS license valid to be used on 2 computers, it is valid until 06/03/2013. If I click on renew exiting license now (before the expiration date has even come close), and added 1 year for it to be used on 4 computers. What happens in this case? ESS license gets update to 06/03/2014 valid to be used on 4 computers? or how does it work? I know this is a complicated question but I would like to know an accurate answer please.
