Redesign, on the contrary, a positive impact on SEO. For example, while maintaining the strategically important elements (URLs, microdata, meta tags, if they're still relevant) - you can add links to social network (if you have pages in social networks), add comments, share, other social reactions for users to add customer-centric things (online advice, the opportunity to request a call back, etc.). In addition, you can greatly improve navigation for the site, adding to the attractiveness of clickable tools (replacing text elements in a graphic), add the speakers (the pop-up menu, slider, accordions), as well as optimize images, changing their format to more modern. During the redesign necessary to improve the adaptability of the site for all mobile devices. And if you are interested in other factors that could be changed in the process of redesign, I recommend reading about the factors of website usability.
