Pulumi has some nice built-ins for reading terraform state, but there doesn't seem to be any officially supported tool to read pulumi state from terraform, which is extremely helpful in migrating from Terraform to Pulumi (unless you migrate all of your infrastructure at once). I created a terraform

data_source

that can read Pulumi state from the Pulumi cloud and open sourced it here: https://github.com/transcend-io/terraform-provider-pulumi I also wrote a blog about its usage, and how it enabled my company to migrate many Terraform modules to Pulumi stacks: https://transcend.io/blog/use-terraform-pulumi-together-migrate-infrastructure-tooling/
