How do I move an existing SVN repository?
1. On your server machine where the repository is now, run
svnadmin dump /path/to/the/svn/repo > mydumpfile
2. Put that file (mydumpfile) somewhere
3. Create a repository in new location.
4. Import the dump file (mydumpfile) by running:
svnadmin load /path/to/repo/on/ < mydumpfile
