If a resource is created with a provider

const foo = new aws.resource(name { provider: my provider })

and that provider information is changed, Pulumi doesn’t seem to recognize that change to the resource. This is helpful in changing accounts for resources or regions on the resource.

Yeah - this is being tracked in https://github.com/pulumi/pulumi-terraform-bridge/issues/14. We can improve this to be "smarter" about what provider changes require replacement (and which dont).

good deal. Glad to know it’s tracked 🙂
