Topic: Ruby 1.8.7 or 1.9.2 or both with RVM for Rails 3 server
I currently have a server with Rackspace that has Ruby 1.8.6, Apache and Passenger to run Rails sites from. My development has moved over to Rails 3 now so I'm going to look at setting up a new server on Rackspace and over the next month look at migrating all the sites over, most are Rails 1.3.5, 1.3.4 based Rails apps.
For a production server for Rails 3 would my best option be to look at installing Ruby 1.9.2 or 1.8.7. Or what are peoples opinions on using RVM on a production server. I've had it suggested to already but was unsure as ideally I'd like to keep my production environment as simple as possible?
