This may well be answered somewhere deep in the bowels of the Google FAQs but I can't find it ...

We have just bought an existing business with an existing website, domain and all. We have renamed the business and created a new domain name. However, we spent quite a bit of money on "goodwill" and we want to continue to pick up business from the old site while running the new one.

The old domain name is now a copy of the new site, both on the same server. What is the best way to go about this? Do I shift the site to a new server and keep the same content on two sites, or is there a better way of avoiding the wrath of the all powerful search engines?

Thanks,

Mike
