How to copy category groups from one site to another sites in Expressionengine

i have have four website for example listed below build using Expression engine with the use of MSM plugin :-

1. site_one


2. site_two


3. site_three


4. site_four

I have developed category group for example on site_one for

example:-

site_one category groups are

1. News (it has sub category i.e. latest,current,top)


2. Business(it has sub category i.e. latest,current,top)



3. Sports (it has sub category i.e. latest,current,top)

   
   
   

   now I want to implement or copy category group with subcategory to all other three sites is there any trick to do this work because EE has no option to it if using any sql quires we can solve this issue or in any other way to do this task.

Thanks in advance
