Hi pulumiers! I looking to move all my ioc company code from TF to pulumi but I wonder is it is possible to start just creating new tiny modules with pulumi and being executed in TF in a transparent way, to make the transition from TF to pulumi easier for product teams

No this isn't possible I'm afraid, the execution engine is completely different

You can read terraform state from Pulumi, so if your projects are split up enough that could work: https://www.pulumi.com/blog/using-terraform-remote-state-with-pulumi/ And there is a community terraform provider that reads Pulumi outputs: https://github.com/transcend-io/terraform-provider-pulumi
