A WordPress plugin which provides a WP CLI command to clone taxonomy data from one taxonomy to another - copies taxonomy terms, term meta and adds terms to posts of a specified type.

Originally written to enable the creation of a "duplicate" taxonomy to enable a client to re-categorise thousands of e-commerce products on a live site without disruption.

wp clonetax <source_taxonomy_name> <target_taxonomy_name> [--post_type=<post_type_name>] [--skip_meta_keys=<key1,key2>]

Need to empty out your target taxonomy when testing?

wp term delete target_taxonomy_name $(wp term list target_taxonomy_name --format=ids)

Supports the --debug switch to give more detailed information.

• Add support for multiple post types.
• Option to store/output $term_map data.
• Should probably make this a WP CLI package.
