Removing trac for a specific SVN and re-install? How?



I have trac structures per SVN. I would like to move my trac structures udner a new domain:

So I need to delete them first? and the re-install? But how wold I do that without re-installing my SVNs?

I think I can svn dump the current ones (or) svn export to somewhere, delte the repo and re-import. I am still experimenting so there is not much in there. So I can re-install SVN+TRAC with one click, clean.

Any other suggestions?
