If you want to redesign your static website and convert it to a content management system (CMS) you’ll have trouble maintaining the same URL structure.
For instance your static page may look something like http://www.domain.com/oldpage.html and your CMS page looks like http://www.domain.com/newpage.
If the URL structures don’t match you may lose all your current search engine rankings for that page unless you redirect it correctly.
What is a 301 redirect?
