Posts and Pages

I have about 800 pages associated with my page Principios activos ; using a form <option value> </ option> where in the web address is .Now I’m embedding another form <option value> </ option> those 800 pages to my website Nombres comerciales ; Would it be appropriate to transfer the contents of the pages to posts, delete the 800 pages and embed the posts in Pricipios activos and Nombres comerciales pages? Would it be helpful or best to leave things as they are? Thanks
