Subversion/Changing Repository URL
From Gentoo Linux Wiki
[edit] Introduction
Sometimes Subversion repositories move to a new machine. Instead of deleting a checked out copy and re-checking out the copy you can simply switch URL of checked out svn copy.
[edit] HOWTO
cd
/var/my_repo
svn switch --relocate
http://current_svn_url
http://new_svn_url ./
This will relocate the url for your subversion repository
