Hi all, is it possible when using one backend to stack reference a stack in another backend?

this might depend on what you’re asking -- if you mean referencing stacks across multiple backends of the same type, that is now no longer needed because you can reference stacks within a backend without name collision https://github.com/pulumi/pulumi/issues/3395 if you mean referencing stacks across S3 and GCS, for example, that is not currently possible.

Thanks, I did mean the latter 🙂
