I'm developing a Wordpress site for a website that already exists (that's not currently using Wordpress). The current website cannot be taken down until the new Wordpress site is ready to replace it. I've read the Moving Wordpress codex article and the Giving Wordpress it's Own Directory codex article but I cannot decide, and do not have enough experience to know, which method would be easier/more efficient when it's time to make the website switch?:
Option 1: Develop the website in a subdomain (ie: http:// wordpress.website.com)
Option 2: Develop the website on a 2nd, temporary domain (ie: http:// w3bsite.com)
Any advice from those who have done either would be appreciated.
P.S. The site has already been built locally, using Xampp, but now needs to be deployed online so others involved in the project can populate the site with content.
