I have two pages on my website that I want to swap. I want page "/alpha" to become "/beta" and "/beta" to become "/alpha." I thought it would be easy enough to simply update the URLs on said pages correct the task. I was wrong.

I changed "/alpha" to "/alpha2," then tried to change "/beta" to "/alpha." I was alerted that "/alpha" already exists and needs to be something different. So "/beta" is now "/alpha1" and "/alpha" is "/beta1." If I type in "/beta" it automatically redirects to "/alpha1."

How do I remove the previous URLs from these pages so I can correct the links?
