I have a situation where i have a lot of tags and i want to add custom taxonomies to sort them. But the thing is when i register new taxonomy i cannot use tag slug.
Example (Tag Taxonomy)
Changed to (Artist Taxonomy)
As you can see, i want to change taxonomy while preserving permalinks. I want to list tags based on couple things. But tags are just tags there is no sorting by type with them. I should have used custom taxonomies from the beginning but its too late now.
If i change tags to new taxonomy it will look like this
And i will have a lot of 404 pages. How do i even redirect 1k pages? Especially since they are just part of the tags. I would really have to add redirects one by one.
