Connect a Duplicate Web Page To Another CMS

Is there an easy way to copy a web page connected to a CMS and connect to another CMS?
The Blog post page is connected to Blog CMS. I want to duplicate the blog post page and connected it to a duplicate CMS of a different name. The Blog posts page has a Lock on the connected CMS. I looked in the CMS to disconnect the items but there are so many. There has to be an easier way. Thanks
