I tried searching across the web, wordpress forums, basically everywhere but am not able to find this

How can I copy Custom Taxonomy categories into another Post Type

I have a Custom Taxonomy YYY under Custom Post Type ZZZ

Now I created a new Custom Post Type KKK which also has many items from YYY

So I created a new Custom Taxonomy LLL under KKK but now I need to copy all content from Custom Taxonomy YYY to LLL.

Is there anyway I can do it without needing to retype the content?

Something like Export all records of Custom Taxonomy and then again Import all values?
