Recently I've got my client's URLs rewritten because of non SEO reasons. Obviously, I had to change the URLs on the menus and on the sitemap, for the new "static" version of these pages.
Common sense dictates that I should redirect the old "dynamic" URLs to the new static ones for SEO purposes, so I can transfer the rankings to those newly created URLs, however that would create an infinite loop between the static and dynamic URLs of every page.
What would be the best SEO practice in this case, to make sure not to lose the rankings and transfer them to the newly created pages?
Please let me know
