: Wordpress - Going from categories to tags I have some aging Wordpress blogs where I made the mistake of creating way too many categories (50+ in some instances). This was, in part, due to

@Dunderdale272

Under your site's Tools > Import menu there is a plugin you can install called Categories and Tags Converter, which once installed will give you control over how to handle categories you might want to convert.

This is a relatively painless process in the 3 times I've used it, but I never concerned myself with migrating older urls. If that's a concern, and the "slugs" for category are the same, and you're running under Apache, some .htaccess directives for the individual categories should do the trick. So, assuming you have urls like:
example.com/archive/category/foo http://example.com/archive/category/bar


And want to change them to:
example.com/archive/tag/foo http://example.com/archive/tag/bar


You would add directives for each one in your .htaccess file, like so:

Redirect permanent /archive/category/bar example.com/archive/tag/bar Redirect permanent /archive/category/foo example.com/archive/tag/foo

Now, that presumes that you want them redirected, and none of your blog authors are going to be adding those categories back!

But generally, this would be the approach that would work.

If you're at all concerned with losing data when you alter content, BACK UP YOUR MYSQL DATABASE. Sorry, I had to yell that. :-) And if it goes haywire then simply restore your database.

If you have linked to those old urls in your content, they'll redirect fine. But you could also run WordPress Search and Replace plugin, which facilitates a migration like that, but again, mind backups especially with the Search and Replace plugin, since it makes its changes with no backup.

WordPress offers an option to convert selected tags to categories, and vise versa. I think it's been done in a way to ensure that no links are broken - redirects are put in place as needed.
