Sandor, re:sharing experiences, if you want to frame some scenarios
you've had trouble with, please feel free to share those. Distilling it
down into a repeatable deployment -> upgrade will help us understand and
account for it. As Tim mentioned, tools like juju-upgrader are generally
candidates for incorporation into juju itself, provided they prove
valuable to the community at large. We always welcome any PR's, but
especially so for improvements that add this functionality.

Hi Sandor,
Streamlining upgrades is definitely on the team's road-map. We are aware
of the juju-upgrader plugin, and will be looking to incorporate some of
that functionality into the core codebase.
The core team has worked on better upgrade testing as part of our CI,
which enables more test scenarios to help discover issues between more
versions.
Cheers,
Tim

Is this shared google doc open for external contributors?
After spending a while upgrading our 2.1.x environments to 2.3.x and
hitting some bugs along the way in staging (see below), I'd agree that
the process needs a bit of love and wouldn't mind sharing some experiences.
Rick mentioned https://launchpad.net/juju-upgrader on the Juju show a
couple of episodes back, but I haven't seen it mentioned anywhere else
yet. Are those tools supposed to deal with some of these issues and
eventually be rolled into juju-core?

I think this UX on the upgrade process has obvious problems. Nobody
should have to guess at what to do, in which sequence.
Can I suggest that we have a shared Google doc to mock up a nice
experience starting with the simple command 'juju upgrade' which then
walks people through the process, including the distinction between
upgrading charms, agents and controllers, as well as the ability to do
aerospace-grade upgrades through live migration to newer controllers?
