I've been building a wordpress site on a subdomain while having my old website in the root directory. Now I have finished the site and would like to move it into the root. Is there a way how to 'redirect' my site so I don't need to move all the files and databases from the subdomain? The address should appear as www.myweb.com, though.

I have these folders in my FTP:
public\_html, \_sub, tmp

The subdomain is currently located at \_sub/wc/

Thanks!
