TOPIC: Copying Websites

I am a 'newbie' so if this has been covered before would someone please direct me to it but I have a couple of different websites and have had reasonable success.  So instead of re-inventing the wheel is there a way to copy the content to a new website?  I know I will have to change some wording so as not to appear to Google as a copy but this would be a whole lot easier than starting all over again.  Any ideas?

Hi Mike,

I need to do it for you as I have to copy the databases over and them make some changes to reflect the new URL. Let me know what the old and new sites and I'll take of it for you. Make sure you've submitted the new sites via the Website Hosting request and changed the name servers to ns1.homeinspectorpro.org and ns2.homeinspectorpro.org
