Current Wordpress site and old website need to move to different directory.

there are two websites on my domain... the old one which is currently at optionsre.com (not a wordpress site) and the new one at optionsre.com/test (wordpress site)

I have built a new wordpress website in a sub-directory called "test" on my domain. This wordpress site needs to move to the root directory of my domain to replace the old website there. However, I also need the old website to be moved to a sub-directory called property-list to be accessed in the future. Both websites need to work and function as they do now once the change has been made.

Please review the links above and make sure you understand the job.
