Help In Transitioning

[circa1850]

Not sure how to do this, although I do have some idea but I want confirmation.

I have a website www.ceuq.com.

I have redesigned it using Joomla.

The test site is www.tlddot.info/joomla.

I am ready to transition the test site over to being the main site.

How can I do this the simplest and easiest way?

Instead of the test site url being www.tlddot.info/joomla it needs to become www.ceuq.com.

PM me or post or do both to get my attention.

Thanks in advance for the tips.
