Category & Page Redirects?

Hi

First of all, thank you for your plugin. I really appreciate it.

I have been using your plugin on client sites for a long time but now face a new challenge.

Here it is…

I have a category, let’s call it http://www.example.com/yellow-banana/post-title/
I also have a page called http://www.example.com/yellow-banana/

I want to change the category slug from /yellow-banana/ to /red-apple/ without affecting the /yellow-banana page.

I tried this:

^/yellow-banana/(.*)
^/red-apple/$1

This correctly deals with the category but unfortunately also affects the page (i.e. the page now redirects to the new category archive.)

How can I redirect all posts related to the new category without affecting the page? Can you please advise?

Many thanks!
