Hello, setting up env and moving the rails application should be simple. I've done it dozen times, you can see my setup script for other env on [login to view URL]
Setting up the env, copy or git cloning from a repository should be simple, but the files might need some syncing.
1. Do you put the attachments on S3 or in the server?
2. What server do you use? Apache + passenger or nginx + unicorn?
Please contact me so we can discuss further.
