I'm working on a site that will be changed incrementally (i.e. first the new Homepage will go live, then product pages, then contact, etc). It will not be a switch-flip, wholesale changeover between the two sites.
The old version is built on WP and the new one will be too, but I don't want to use the old files and install, but rather want to start with a fresh install. What are my options for having them coexist on the server and have some pages served from one install and some from another?
This is not a multisite setup as both sites will need to use the same domain.
