Hi Bogi,

Generally I think it's could be a good idea to change the current upgrade
concept, and to store the SQL commands in versioned chain of files.

Although I'm a bit concerned about the validation and testing of such a
change. I think it would be great if the community could discuss your
thoughts in the related topic.

If you could share with us how do you plan to ensure that the new approach
is working in a robust way ( not having inconsistent behavior in the web of
objects ( e.g. NPE, illegal states, illegal arguments ), what to do in case
of missing file(s), what to do in case of failing step(s), how do we ensure
the system does not end in an inconsistent state, how do we ensure in case
of failure the system remains still in a usable state as before, etc. )
that would be awesome.
