Tell us what you are trying to do?
I didn't think it through when I began to use categories in a new post type I made with Toolset. Now I have made 21 categories placed in "Categories" (standard from WordPress) but I would like to move these 21 categories to a new category named "Lifters Categories"
Do you have any idea to do that without crashing alle the views I have build on the site so far?
This is not something that can be done with our Toolset plugins. In order to do this you will either need to recreate the taxonomies manually in your new taxonomy or try using a plugin that can facilitate the move.
