For all those who're seeking an alternative to XP-Dev that supports SVN (in light of the recent sad events and termination of its work), there's a source code management platform called RhodeCode for behind-the-firewall Mercurial, Git, and SVN. It is open source, secure, and provides centralized control over distributed code repositories. The team is ready to assist you with migrating your repositories and ensuring a smooth transition.
