Usage

Usage is simple:

cvs -d /path/to/cvs/repository init
python rcs4cvs2svn /path/to/rcs/project /path/to/cvs/repository

There are a couple of options, for more information run:

python rcs4cvs2svn --help

Tutorial

This section describes how to migrate an RCS repository to CSV and then to Subversion.

First, create a simple RCS repository for a project called “hello” which contains a single file, “hello.txt” with 2 revisions:

mkdir -p hello/RCS
cd hello
echo "hello world!" >hello.txt
echo "Added greetings.\n." | ci -u hello.txt
co -l hello.txt
echo "hello space!" >>hello.txt
echo "Added more greetings.\n." | ci -u hello.txt

Next, create a new CVS repository which will act as destination:

cvs -d /tmp/hello_cvs init

Now migrate the the RCS repository to CSV.

python rcs4cvs2svn.py hello/ /tmp/hello_cvs/

Because CVS still is a very dated way to manage a software project, let’s move on to the next step of evolution: Subversion. You will need cvs2svn, available from <http://cvs2svn.tigris.org/>.

While there are several ways to convert CVS to SVN, the easiest for our task is to simple create a SVN dumpfile containing the CVS as trunk:

cvs2svn --trunk-only --dumpfile hello.dump /tmp/hello_cvs/

Now you can create a SVN repository and load the trunk into it:

svnadmin create /tmp/hello_svn/
svnadmin load /tmp/hello_svn/ <hello.dump

Moving on to even more advanced SCM systems is left as an exercise to the reader.
