301 Redirect Help

Hi guys and girls!

Just a quick question re: 301 redirects.

When setting up a 301 to change a single page URL, do I first have to change the URL path in the designer, then set up the 301 redirect in the site settings?

When I attempt to setup the redirect (without first changing the path in designer), I get an error
“The old url is already a page on this project”

I’ve had a look through other topics but can’t find anyone who’s asked this question.
Just wanted to confirm, as I don’t want to make any moves that will damage my SEO efforts!

Many thanks for your help!

Yes, you can do this without publishing.

This restriction/validation is to avoid redirecting a valid page.

@samLiew, thanks mate, much appreciated.
