You cannot "upgrade" your VSD website in RSD. You need to rebuild your website within RSD. Visual Site Designer builds websites using absolute positioning. This means everything has a fixed place within the page and cannot be adjusted based on the viewer’s device size (desktop, tablet, mobile phone, etc.). Absolute positioning does not allow for a modern, fluid responsive design. That means your mobile users (almost 51% of all internet traffic today) are getting an unfriendly browsing experience on your website. Google also now gives priority ranking to websites that are device-agnostic. This mean you are going to lose page rank automatically because you don’t have a responsive website. For this reason, we have decided to discontinue Visual Site Designer

Learning responsive design can take a little time to master. But we have a bunch of articles on RSD to help you get more familiar with how this app works. Our Quick Start Guide is very helpful when getting started. We also have a new step-by-step tutorial which will walk you through transforming a static site to a responsive one that is perfect when you are just starting out. http://www.coffeecup.com/help/articles/1430

If you are a visual based learner, a new tutorial has been posted that breaks down the creation of a responsive page in just 5 steps. This article is unique as it includes 8 instructional videos. Check it out at: http://www.coffeecup.com/help/articles/1449

Apparently my intuition has left the building. I struggled with the RSD beta trial for several days, watched the tutorials, read the tips & still remain mystified. I've had a long, successful run with VSD but it may be time to retire & turn my clients over to someone who will charge a great deal more for the latest & greatest "must haves." Sorry my bitterness is showing.

Roberta, I had the same concerns. I can tell you how I handled this changeover. Email me at bill@quickbizwebsites.com
