[PLUG] Ruby / Rails Backwards Compatibility

[Rich Freeman <r-plug@thefreemanclan.net>]

I've managed to encounter a Ruby/Rails application that is running on
a fairly old version of both, and I've been told that it has been
difficult to get it to run on a supported version of both.

I figured I'd see if anybody on the list has much experience with
Ruby/Rails and whether this is a common problem.  Is it generally
difficult to get an application to run on a newer version of
Ruby/Rails than what it was originally developed on?  What is the
upstream policy on backwards compatibility?  How do companies that use
these technologies live with these kinds of issues?

I'm trying to get a sense for whether it makes more sense to do a
one-time effort to port things, and how big that is likely to be, or
if that is just kicking the can a year or two and we really need to
think about the sustainability of the platform.  Where I work
Ruby/Rails really isn't a thing, which is also a problem since we
don't just have teams of people sitting around who can work on it.
