Steps to Migrate Ruby on Rails App from x86 Ubuntu EC2 to Graviton Instance

I need detailed steps to migrate my Ruby on Rails application from an x86_64 Ubuntu EC2 instance to a Graviton-based instance. Specifically, I need guidance on how to verify compatibility of the Rails app and its dependencies with the ARM architecture, any preparatory steps needed on the current x86_64 environment, and detailed instructions to move the Rails app to the Graviton instance, including any necessary configuration changes. Additionally, I seek advice on testing the Rails app on the Graviton instance to ensure smooth operation and any performance optimizations or considerations specific to running on Graviton. Any pointers or documentation on this migration process would be very helpful. Thank you!
