I have an existing website built in Wordpress that displays house plans and has a builders directly with subscription function.

I am planning on cloning this site and modifying into an ecommerce site selling house plans. Thus the plans will be the same on both sites. This site will operate like a market place where architects can add there own plans and sell them.

Need:

I need a solution that will move data between websites so I only put it in once, and it can be pushed to both website 1 and website 2.

I need the technology stack and workflow mapped out.
