TFE: import Terraform resources when VCS or API driven approach is used

Intro

This manual is dedicated to resolve issue with importing resources into Terraform Enterprise state when VCS or API driven approach is used

Problem description

When VCS or API driven approach is used it is not possible to modify state to import resources. However, there is still a way to do it. 

Solution

1. Download the state file

2. Reconfigure the code to not use any remote backend

3. Run the terraform init locally with the state file still in the same directory

4. Execute the tasks to import or remove the resource from the state file

5. Re-upload the state file via Terraform Init

6. Reconfigure the Terraform Code with the remote backend again

7. Re-run the terraform init (It should offer the option to migrate the backend) via State Version

8. Use this KB to create a new state version

9. Reconfigure the remote backend

10. Put the local state file aside

11. Re-run the terraform init
