Best way to develop site with existing site up?
I have never done it this way but I need to create a complete site with databases, store, forms etc etc but keeping the existing website up until I am finished. I usually was able to just take down the site and upload as I go but not this time.
I have a testing server setup but when I test it live it just shows the CMS install screen.
So what is the best way to develop this new site and see it live without taking down the existing one and being able to easily transfer it when it's done?
