copying check boxes from one domain to another

I need to copy check boxes from one url to another one, both url have the same structure but have difference in name, Url, Category, Date, etc.. Lets name them as Url1 (for url copying from) and Url2 (Pasting data to) so what I want to do is just copy all the data of Check boxex of Url1 to Url2, do not want any other thing just check boxex required.
