That's an interesting point. Because Rails 3 (and by extension, in my mind, any Gem that purports to be compatible with Rails 3) supports both 1.8.7 and 1.9.2, I thought that there would not be any difficulty there. I am using a fairly short list of Gems, all of which are running without apparent errors on the server. > > Did you not test your application in a staging environment before > updating the Ruby on your production server?

I could not get 1.8.7 to install properly on the server in question, I had multiple problems getting Rubygems and Passenger to install until I moved to 1.9.2. Rolling the server back to 1.8.7 is not a good option for me. What I can do is RVM up to 1.9.2 on my Mac, and re-run my tests there. I do have a complete suite of tests, which pass in 1.8.7. What I don't have yet is a development or staging server with 1.9.2.
