Add .html extension to only one page in my WordPress site

We had an old site that had html pages in it. One of the pages in that site was linked to from many other sites.

Now we moved to a WordPress site, and we created a page with that name, but of course it doesn’t have the “.html” extension, so links to that page lead to an empty page…

I saw a plugin that adds html extesnsions to all pages, but I don’t want that – I have only one page to which I want to add .html.

What can I do to accomplish this?

I would just add a rewrite rule to your .htaccess file of something like:

Redirect 301 /oldpage.html http://domain.com/newpage/
