Copy or convert terms between taxonomies.
Taxonomies include categories, tags and any other custom taxonomies that may be present with your active theme and plugins.
This plugin, based on Categories to Tags Converter, allows you to copy (duplicate) or convert (move) terms from one taxonomy to another or to multiple taxonomies, while maintaining associated posts.
I used this to convert about 8 categories to tags. It errored and when I checked the categories had been deleted but the tags hadn't been created.
Total lifesaver but it does not carry over the hierarchy of the sub-category relationship...gotta have that if you are going to the trouble of copying everything else, right?
- Moved copy to/to taxonomy field to above terms list
- Tested with WP 3.7.1
