Moving from sub-domain to domain

I have had a site running for a few years at and I’ve now almost completed a new site which I’ve been testing at

Once the new site is ready, I want to:
make it appear at
have the old site appear at

The old site is very large in terms of number of files etc. and so I’d rather not have to move it. Both sites are mambo/Joomla sites.

Any suggestions would be much appreciated.



FTP in and rename both: to ask-asus.old to
ask-asus.old to

Be sure to edit any config files to reflect these changes.
