I have a rails app on an old Ubuntu server I need to move onto a new machine.
I haven't worked with ruby on rails so I don't really know anything about the structure of the app.
I want to load this onto an Ubuntu 8.04 AMI on Amazon EC2 and am looking for any information regarding the migration process such as:
Do I copy over the entire folder defined as the application root in the mongrel config (for ex: /u/apps/myapp/current) or just certain folders?
Am I looking for trouble if I go with the latest versions of ruby and the various gems?
Any general gotchas to look out for in the process.
Current server information:
root@webnode001:/# cat /proc/version
