Revamping Site - How to not lose ranking?

Hi guys,

I'm revamping my site at the moment and am re-creating every page with the same URL.

Once I bring it live, what do I need to do to maintain ranking? Do I need to do some sort of redirect, and if so how? I think something like redirect a.com/title1 to a.com/title1 is a bit weird.

Thanks

As long as you keep the same internal link structure you should be fine
