WordPress Name Change

Hi,
Need some help and advice. I'm going to change the name of my website Bare-Assed.com to Lads-Mag.com however all the site is with the prefix of Bare-Assed for example:
http://bare-assed.com/kevin-webster-corrie-star-gets-jailed/
How would I change Bare-Assed so it's replaced with Lads-Mag without causing any issues to my articles, photo's, pages etc?
Help would be great as I don't want to start all over again.
Regards
Steve
