As I mentioned in my reply to @dazzling-author-49810, if you're using the Pulumi Service as your backend it looks like you can see old stack states in the Activity section: https://www.pulumi.com/docs/intro/pulumi-service/projects-and-stacks/#stack-activity I can't confirm that though as I'm using Azure as the state backend, and it no longer seems possible with Azure without some custom coding.
