+# Step 4: update provider sources to the new format
+
+Terraform 0.13 introduced a new registry for managing provider releases. This makes it easier to publish and distribute
+third party providers. As a part of this, Terraform changed the way providers are tracked in the state file. When
+running `terraform init` for the first time on a module that has been updated from <0.13 to 0.13+, you might notice
+Terraform installing two providers:
+
+- `-/PROVIDER`
+- `hashicorp/PROVIDER`
+
+The first one is used to track legacy provider sources that are mentioned in the old state file, while the latter is
+what is configured in your module using the new `required_providers` blocks when you upgraded your modules in step 2.
+
+To avoid conflict between the two providers, it is recommended to update your state file to use the new provider
+references. This can be done by using the `state replace-provider` command.
+
+For each provider your module uses, run the following command:
+
+```
+# NOTE: Use terragrunt instead of terraform if you are using terragrunt to manage your resources.
+terraform state replace-provider -- -/PROVIDER registry.terraform.io/hashicorp/PROVIDER
+```
+
+For example, if your module uses `null` and `aws` providers, you will want to run:
+
+```
+terraform state replace-provider -- -/null registry.terraform.io/hashicorp/null
+terraform state replace-provider -- -/aws registry.terraform.io/hashicorp/aws
+```
