The release of OpenNebula 2.0 consumed too much effort so we did not have
time to develop tools for migrating from 1.4 to 2.0. That was a
difficult decision, considering the production deployments of OpenNebula. We
thought that the new features and scalability and general stabilization of
the code was worth a less straightforward update procedure. We'd hope that
we made the right decision.

Fortunately, OpenNebula has a great community and there are a couple of
scripts contributed by Marlon Nerling (THANKS FOR THIS!).

As I said we will work into smoother upgrade processes in future versions
and specially within the 2.x series.

We are committed to this and will support the development of any tool to do
this automatically.

I am glad that Ubuntu users can now get the latest OpenNebula software from
the repositories, and the fact that 1.4 did not make the repos makes things
even more difficult. OpenNebula 1.2 is so different from 2.x (even from 1.4)
that the automatic migration process is not easy.  We could think of this if
there are users still running 1.2 in production


Cheers
