cvs2svn is a tool for migrating a CVS repository to Subversion, git, or Bazaar. The main design goals are robustness and 100% data preservation. cvs2svn can convert just about any CVS repository we've ever seen. For example, it has been used to convert gcc, FreeBSD, KDE, GNOME, PostgreSQL…
cvs2svn infers what happened in the history of your CVS repository and replicates that history as accurately as possible in the target SCM. All revisions, branches, tags, log messages, author names, and commit dates are converted. cvs2svn deduces what CVS modifications were made at the same time, and outputs these modifications grouped together as changesets in the target SCM. cvs2svn also deals with many CVS quirks and is highly configurable. See the comprehensive feature list.
You can get the latest releases from the GitHub releases page. Please read the documentation and the FAQ carefully before using cvs2svn.
For general use, the most recent released version of cvs2svn is usually the best choice. However, if you want to use the newest cvs2svn features or if you're debugging or patching cvs2svn, you might want to use the master version (which is usually quite stable). To do so, use Git to clone the repository, and run it straight from the working copy.
This repository contains a Dockerfile that can be used to create a
docker image in which cvs2svn can be run. (It has some dependencies
that are no longer easily installable, so this is probably the easiest
way to run cvs2svn.)
