Fix Terraform Provider Path in State

Fixing Terraform provider paths in state might be required after upgrading to 0.13-0.14 if your prior state has the following paths.

First, get the terraform providers from state using: terraform providers

The output should look similar to this:

To fix these, try running the commands to fix state. Please adjust to the required providers your state uses, and make sure your tooling has a backup of the state file in case something goes wrong. Terraform Cloud should have this backed up automatically if it's your backend.

terraform state replace-provider -- registry.terraform.io/-/aws registry.terraform.io/hashicorp/aws
terraform state replace-provider -- registry.terraform.io/-/random registry.terraform.io/hashicorp/random
terraform state replace-provider -- registry.terraform.io/-/null registry.terraform.io/hashicorp/null
terraform state replace-provider -- registry.terraform.io/-/azuredevops registry.terraform.io/microsoft/azuredevops

The resulting changes can be seen when running terraform providers and seeing the dash is now gone.

Upgrading to Terraform v0.13 - Terraform by HashiCorp

If you have multiple workspaces in the same folder, you'll have to run fix on their seperate state files.

This is an example of a quick adhoc loop with PowerShell to make this a bit quicker, using tfswitch cli tool.

tf workspace list | ForEach-Object {
    $workspace = $_.Replace('*','').Trim()
    Write-Build Green "Selecting workspace: $workspace"
    tf workspace select $workspace
    tfswitch 0.13.5
    tf 013.upgrade
    tfswitch
    tf init
    # Only use autoapprove once you are confident of these changes
    terraform state replace-provider -auto-approve -- registry.terraform.io/-/aws registry.terraform.io/hashicorp/aws
    terraform state replace-provider -auto-approve -- registry.terraform.io/-/random registry.terraform.io/hashicorp/random
    terraform state replace-provider -auto-approve -- registry.terraform.io/-/null registry.terraform.io/hashicorp/null
    terraform state replace-provider -auto-approve -- registry.terraform.io/-/azuredevops registry.terraform.io/microsoft/azuredevops
    tf validate
}
