I transitioned without a problem. The file organization is much much better as is the ability to customize. Definitely not a refresh but a whole new site...I am very happy at the moment. I also feel better about the pricing now since time is money and they just saved me a whole lot of time!
alexzn: In my experience the redesign is a disaster, because it breaks the continuity with the old site and there is no obvious way to keep the structure. if you have large heavily structured site, you need to essentially rebuild from the ground up. For a pro-oriented site this is rather amateurish. The customization instructions also are not very clear.
How much experience have you had with it? I did not see a link to your site in your profile.
