While upgrading following are the questions that are frequently asked

1. Can I upgrade from 2003 – 2013? The answer is no direct upgrade possible and it would be a very painful experience – better to re-design and redo in 2013.

2. Can I upgrade from 2007 - 2013.The answer again is no direct upgrade possible. You need to go from 2007 to 2010 to 2013. 
So what about the licenses then. Do I need to purchase both licenses?

You don't need to purchase both licensed. You can buy a 2013 license, downgrade to 2010 perform the 2007 to 2010 upgrade and then upgrade the license to 2013.

3. What care do I need to take to upgrade from 2010 – 2013?
