Publishing wordpress files

Thanks,
The doc you have indicated suggest that the DB is moving as well, but,
I want to keep the same DB (I’ve got only this one at http://www.s297253748.websitehome.co.uk/)
basically I’d like to keep everything as it is only that when the correct URL (http://www.whassupdorch.co.uk/) is typed the site shows as on the development site.

Sorry I’m not sure I’m explaining myself correctly:

The DB is on server A (dev URL)
The public site is on server B (correct URL)

I want B to display the content of DB A. (B has no DB of it’s own).

Would a simple DNS pointing do the trick?

Thanks. I take it DNS pointing will not solve the issue?
