Upgrading Ubuntu from 12.04 to 14.04

[Amos Shapira]

Beyond the original specific question - upgrades like this should be tested
using a Vagrant box, preferably also using an automatic provisioning tool
like Puppet (my personal preference) or Chef (obligatory mention) and
automatic testing using things like Cucumber, Spec, ServerSpec or perhaps
other testing frameworks.

That way you can write the tests to verify your current setup and repeat
the verification after the update.

Also - once you have automatic provisioning and testing in place, you
should consider treating the servers as immutable, i.e. once they are setup
they are not upgraded in-place but rebuilt whenever such a large change is
required. This way you are sure that what you run is exactly what you
tested in your Vagrant environment and what will be re-installed in case of
a disaster.
