How can I safely migrate from google_project_iam_policy resources to google_project_iam_member?












2















I have a TF project which currently uses a single google_project_iam_policy resource, and would like to transition to using
google_project_iam_member.



The documentation warns:




google_project_iam_policy cannot be used in conjunction with google_project_iam_binding and google_project_iam_member or they will fight over what your policy should be.




Is there a safe path to migrate from one style to the other?

          google_project_iam_policy might fight with google_project_iam_binding and google_project_iam_member, but it should be possible to use them concurrently for a brief period (provided they contain the same values).



          I haven't tested this, but I think it should be possible to do something like:




          1. Mirror the current google_project_iam_policy permissions into a new set of google_project_iam_binding or google_project_iam_member resources

          2. Run terraform apply to add the new resources to your terraform state file

          3. Remove the old google_project_iam_policy resources from your terraform config, but don't run terraform apply

          4. Run terraform state rm <resource-name> for each of the old google_project_iam_policy resources

          5. Run terraform plan and confirm no changes are planned
