Assume I have an SVN repo accessed via http at http://svn.example.com/svn/myapp.
The URL http://svn.mycompany.com/svn/myapp is an alias for the above (ie same server, same login details). How do I tell an svn client that's already checked out a working copy to use the new URL given that nothing apart from the URL is changing?
As an aside, if the new URL was on a different server with different user/pass but contained an identical repository (with a view to moving to a new host), how would that affect things?
