It's about the sixth years since my first commit 
using Subversion,
Moving from CVS to Subversion was really amazing, Subversion was
superior in many ways and it served me well. But the age of centralized
version control systems is over, we need much more powerful VCSs
to deal with huge projects. Now days we should to be able to work with 
anyone, on anything, anywhere ,
at anytime, and also keep track of all this activities.
As part of
 my research project (Comparing Popular Version Control Systems) i decided to start with Bazaar and 
migrate one of my Subversion Sourceforge projects to this new VCS 
in order to have a better understanding of how it actually works. And 
also test the migration utilities because if you can't migrate your 
code's history then that would be a huge 
problem.
