Today I have migrated a CVS repository to subversion. It was quite easy with a cvs to subversion migration howto.
The stuff I transmitted was this website. About three months ago I started using subversion. At first it was a try only, but now I use it for three projects and a website. I really like it. The nicest commands are the
status command. This is stuff that programmers really need to know and use, even if you're one programmer working a project.
