I want to change the domain name of my web site and move it to a different IP, I don't want crash the program, what is the best way to do this?

hmm i always use phpmyadmin to take a mysql dump, downlaod all files from old server... then upload them all up to the new server, then you need to make new database and import the mysql dump.

Maybe need to chmod the files again.
