[Rails] Re: How would you upgrade

We have a very large application with probably close to 100K lines of

we make a little progress it seems Rails or Ruby has released a new
version, and I can't foresee us every getting caught up as our resources
are rather limited.  I have one assistant working on upgrading and I'm
always working on bugs and feature requests.  I know we should freeze
the feature requests.....  but a full rewrite is so far away, a total
freeze won't be accepted.

 Just so you know the update from rails 2.3.x to 3.0 is way bigger and more difficult than any of the other upgrades I've ever done (I've been using rails since 1.0), 3.0 to 3.1 and 3.1 to 3.2 are much much easier. 4.0 will also be a simpler upgrade than 2.3 to 3.0.

Similarly ruby 1.8.7 to ruby 1.9.x is a much bigger change ( in terms of work required) than 1.9 to 2.0.

In a nutshell, don't lose hope!
