Subversion has been removed from the DreamHost panel. If you had previously configured Subversion on your domain, it will continue to function normally.
If you have an SVN repository that you wish to migrate to a new server, you should first create a dump file. Once that is created, proceed with the steps below to import it into your new repository on your new server.
The commands below assume that the SVN repo you previously backed up is named dumpfile.gz. The file path for the 'svnadmin load' command assumes that your new SVN repository is in the /home/username/svn/ directory on your new server and that it's named New_Repo.
