Just as immortal says you upgrade on the host you have today. When thats done and all backups is taken for the move just...move it to the new host. Should work just fine unless you have some very specific setup on the hosts server your on today but I guess the host should be able to help you with that.

Good luck and remember to do the upgrade on a testsite first just in case it screws up any of your installed skins/mods etc.
