rebuilding the cloud stack with a different model

what is the best way to rebuild the cloud stack with different options in AWS?

let's say a new stack comes out that you offer and new model's come out... what is the best way to rebuild while keeping all of my already existing output and data?

The issue names AWS but does not identify a file, test, or entry point. Start by clarifying which new stack or model options must be supported and how existing output and data should be preserved; completion would require an agreed migration or rebuild workflow.
