---

Terraform Version

• 0.9.8

Affected Resource(s)

• azurerm_storage_account

Expected Behavior

Since the account type can't be updated, I expected terraform to replace the resource instead.

Actual Behavior

What actually happened?

* module.workers.azurerm_storage_account.tectonic_worker: 1 error(s) occurred:

* azurerm_storage_account.tectonic_worker: Error updating Azure Storage Account type "c99c88ef": storage.AccountsClient#Update: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="StorageAccountTypeConversionNotAllowed" Message="Storage account type cannot be changed to Premium_LRS."

Steps to Reproduce

1. Create a Standard_LRS storage account with terraform and terraform apply
2. Change the tier to Premium_LRS storage account and terraform apply
