terraform - 升级 terraform provider 导致 "invalid resource instance data in state"错误

Question

我将 Terraform AzureRM 提供程序从 1.44 升级到 2.23。 Terraform 版本是 0.13.0。有趣的是，现在我尝试运行 terraform plan我收到多个“状态无效的资源实例数据”错误。
它们看起来像这样:

Error: Invalid resource instance data in state

  on .terraform\modules\redacted\terraform\modules\keyvault\main.tf line 1:
   1: resource "azurerm_key_vault" "keyvault" {

Instance module.redacted.module.keyvault.azurerm_key_vault.keyvault data could
not be decoded from the state: unsupported attribute "sku".

我的状态文件在 Azure 存储中。在查看状态文件时，我们看到了问题:

    {
      "module": "module.redacted.module.keyvault",
      "mode": "managed",
      "type": "azurerm_key_vault",
      "name": "keyvault",
      "provider": "module.redacted.provider.azurerm",
      "instances": [
        {
       ...
            "sku": [
              {
                "name": "standard"
              }
            ],
            "sku_name": "standard",
      ....

为 keyvault 定义 sku 的最新方法是使用“sku_name”属性。但是旧的方式已经卡在状态文件中，现在正在引起问题。
升级提供程序以便清除状态文件的首选方法是什么？或者这是必须手动完成的事情？

Answer 1

注意:我无法重现该问题。我从 1.44.0 到 2.23.0。我看到 sku[{}] 状态信息在状态文件中。当我使用 2.23.0 运行应用程序时，它被删除了。
最安全的做法是进行备份，删除状态并导入它。
删除状态并导入它(升级前检查状态会产生错误)

▶ terraform state show azurerm_key_vault.example 
unsupported attribute "sku"
# azurerm_key_vault.example:
resource "azurerm_key_vault" "example" {

▶ terraform state rm azurerm_key_vault.example
Removed azurerm_key_vault.example
Successfully removed 1 resource instance(s).
▶ terraform import azurerm_key_vault.example /subscriptions/redacted/resourceGroups/example-resources/providers/Microsoft.KeyVault/vaults/pearcec
azurerm_key_vault.example: Importing from ID "/subscriptions/redacted/resourceGroups/example-resources/providers/Microsoft.KeyVault/vaults/pearcec"...
azurerm_key_vault.example: Import prepared!
  Prepared azurerm_key_vault for import
azurerm_key_vault.example: Refreshing state... [id=/subscriptions/redacted/resourceGroups/example-resources/providers/Microsoft.KeyVault/vaults/pearcec]

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.


▶ terraform state show azurerm_key_vault.example | Select-String "sku"
InputStream:12:    sku_name                        = "standard"
