Upgrading domain

[squiggler]

Okay, so I have a site on free hosting. Eventually, I'll want to upgrade to paid hosting. My url would change from this: koiadopts.x10.mx
to this: koiadopts.com

How badly would this screw up the coding and content of the site, and what would make the transition as smooth as possible? Thank you so much in advance for all your help.

It should not screw up your site in any way unless you have hardcoded your original domain url in part of your script or database.

Okay, thank you. I'm so happy about that! Will I need to change any of the files at all?
