Probably there is no need to switch from CVS to subversion, but I’m starting to forget the options of the cvs command, therefore decided to migrate. Unfortunately, there is no button “convert” on the site, therefore I had to find how to do it manually.

A quick search gave a migration notes of Audacity: CVS To SVN Migration. To get a better understanding what is happening, I read the following documents:

* Version Control with Subversion / Converting a Repository from CVS to Subversion
* cvs2svn Documentation

The dump was easy to produce:

$ rsync -av --delete-delay rsync://PROJECT.cvs.sourcefor
   ge.net/cvsroot/PROJECT/* PROJECT-cvsbackup/

$ cvs2svn --dumpfile=svndump PROJECT-cvsbackup > cvs2svn.log

The task of importing the dump was more challenging, but also easy solved thanks to the sourceforge documentation: Managing your Subversion Repository with adminrepo

This moves the dump on the sourceforge servers and logs in:

$ rsync -aiv svndump USER,PROJECT@web.sourceforge.net:.
$ ssh -t USER,PROJECT@shell.sourceforge.net create

And this what happens after logging in:

$ mv /home/groups/P/PR/PROJECT/svndump .
$ adminrepo --checkout svn
$ rm -rf /svnroot/PROJECT/*
$ svnadmin create /svnroot/PROJECT/
$ svnadmin load /svnroot/PROJECT < svndump
$ adminrepo --save

Project options

Remembered after writing this post: one must to activate subversion before doing the conversion:

Project admin -> Feature settings -> Available Features

After conversion, disable CVS.
