<!-- Hi there, Thank you for opening an issue. Please note that we try to keep the Terraform issue tracker reserved for bug reports and feature requests. For general usage questions, please see: https://www.terraform.io/community.html. If your issue relates to a specific Terraform provider, please open it in the provider's own repository. The index of providers is at https://github.com/terraform-providers . --> ### Terraform Version <!--- Run `terraform -v` to show the version, and paste the result between the ``` marks below. If you are not running the latest version of Terraform, please try upgrading because your issue may have already been fixed. --> ``` Terraform v0.12.18 + provider.alicloud v1.67.0 ``` ### Terraform Configuration Files <!-- Paste the relevant parts of your Terraform configuration between the ``` marks below. For large Terraform configs, please use a service like Dropbox and share a link to the ZIP file. For security, you can also encrypt the files using our GPG public key. --> ```hcl ``` ### Debug Output <!-- Full debug output can be obtained by running Terraform with the environment variable `TF_LOG=trace`. Please create a GitHub Gist containing the debug output. Please do _not_ paste the debug output in the issue, since debug output is long. Debug output may contain sensitive information. Please review it before posting publicly, and if you are concerned feel free to encrypt the files using the HashiCorp security public key. --> ### Crash Output <!-- If the console output indicates that Terraform crashed, please share a link to a GitHub Gist containing the output of the `crash.log` file. --> cmd output ``` terraform init \ -backend-config "bucket=terraform-bucket" \ -backend-config "tablestore_table=terraform_table" \ -backend-config "region=cn-zhangjiakou" \ -backend-config "key=alicloud" \ -backend-config "access_key=$TF_VAR_alicloud_access_key" \ -backend-config "secret_key=$TF_VAR_alicloud_secret_key" \ Initializing the backend... Backend configuration changed! Terraform has detected that the configuration specified for the backend has changed. Terraform will now check for existing state in the backends. Terraform detected that the backend type changed from "s3" to "oss". Do you want to migrate all workspaces to "oss"? Both the existing "s3" backend and the newly configured "oss" backend support workspaces. When migrating between backends, Terraform will copy all workspaces (with the same names). THIS WILL OVERWRITE any conflicting states in the destination. Terraform initialization doesn't currently migrate only select workspaces. If you want to migrate a select number of workspaces, you must manually pull and push those states. If you answer "yes", Terraform will migrate all states. If you answer "no", Terraform will abort.
