how to change the orgin remote

You can

git remote set-url origin git://new.url.here
(see git help remote) or you can just edit .git/config and change the URLs there. You're not in any danger of losing history unless you do something very silly (and if you're worried, just make a copy of your repo, since your repo is your history.)
