There is a great piece by Adam Swift on making the move to Subversion as a version control system at O’Reilly’s MacDevCenter.com (http://www.macdevcenter.com/pub/a/mac/2004/08/10/subversion.html?page=1).
This is a topic that has been run though before in the SitePoint forums where there are some Subversion fans. I am just now finally taking the leap away from CVS to Subversion — so this article has excellent timing.
Be sure to scan through the docs over at www.securityfocus.com as some vulnerabilities remain on Subversion. Many vendors have attempted to address them and have issued patches or updates.
Subversion’s project home page can be found at http://subversion.tigris.org/.
