I currently have a 1500 page site in ModX that I am looking to move to a Concrete5 site. Developers are currently designing the theme and skins for me, but I will need to transfer the content, linking, optimization, etc from the ModX site to the Concrete 5 site.

Is there a way to do this without manual entry of all of the information above? Is there an automated/simplified process to transfer content from the ModX site to the new, Concrete5 site, e.g., file transfer?
