 * resource/aws_db_instance: With the retirement of EC2-Classic the `security_group_names` attribute has been removed ([#30966](https://github.com/hashicorp/terraform-provider-aws/issues/30966))
+* resource/aws_db_instance: `id` is no longer the AWS database `identifier` - `id` is now the `dbi-resource-id`. Refer to `identifier` instead of `id` to use the database's identifier ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
 * resource/aws_default_vpc: With the retirement of EC2-Classic the `enable_classiclink` and `enable_classiclink_dns_support` attributes have been removed ([#30966](https://github.com/hashicorp/terraform-provider-aws/issues/30966))

 * data-source/aws_service_discovery_service: The `tags_all` attribute has been deprecated and will be removed in a future version ([#31162](https://github.com/hashicorp/terraform-provider-aws/issues/31162))
 * resource/aws_api_gateway_rest_api: Update configurations with `minimum_compression_size` set to pass the value as a string. Valid values remain the same. ([#30969](https://github.com/hashicorp/terraform-provider-aws/issues/30969))
 * resource/aws_autoscaling_attachment: Update configurations to use `lb_target_group_arn` instead of `alb_target_group_arn` which has been removed ([#30828](https://github.com/hashicorp/terraform-provider-aws/issues/30828))
+* resource/aws_db_event_subscription: Configurations that define `source_ids` using the `id` attribute of `aws_db_instance` must be updated to use `identifier` instead - for example, `source_ids = [aws_db_instance.example.id]` must be updated to `source_ids = [aws_db_instance.example.identifier]` ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
+* resource/aws_db_instance: Configurations that define `replicate_source_db` using the `id` attribute of `aws_db_instance` must be updated to use `identifier` instead - for example, `replicate_source_db = aws_db_instance.example.id` must be updated to `replicate_source_db = aws_db_instance.example.identifier` ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
+* resource/aws_db_instance: The change of what `id` is, namely, a DBI Resource ID now versus DB Identifier previously, has far-reaching consequences. Configurations that refer to, for example, `aws_db_instance.example.id` will now have errors and must be changed to use `identifier` instead, for example, `aws_db_instance.example.identifier` ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
+* resource/aws_db_instance_role_association: Configurations that define `db_instance_identifier` using the `id` attribute of `aws_db_instance` must be updated to use `identifier` instead - for example, `db_instance_identifier = aws_db_instance.example.id` must be updated to `db_instance_identifier = aws_db_instance.example.identifier` ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
+* resource/aws_db_proxy_target: Configurations that define `db_instance_identifier` using the `id` attribute of `aws_db_instance` must be updated to use `identifier` instead - for example, `db_instance_identifier = aws_db_instance.example.id` must be updated to `db_instance_identifier = aws_db_instance.example.identifier` ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
+* resource/aws_db_snapshot: Configurations that define `db_instance_identifier` using the `id` attribute of `aws_db_instance` must be updated to use `identifier` instead - for example, `db_instance_identifier = aws_db_instance.example.id` must be updated to `db_instance_identifier = aws_db_instance.example.identifier` ([#31232](https://github.com/hashicorp/terraform-provider-aws/issues/31232))
 * resource/aws_docdb_cluster: Changes to the `snapshot_identifier` attribute will now trigger a replacement, rather than an in-place update. This corrects the previous behavior which resulted in a successful apply, but did not actually restore the cluster from the designated snapshot. ([#29409](https://github.com/hashicorp/terraform-provider-aws/issues/29409))
 * resource/aws_dx_gateway_association: The `vpn_gateway_id` attribute has been deprecated. All configurations using `vpn_gateway_id` should be updated to use the `associated_gateway_id` attribute instead ([#31384](https://github.com/hashicorp/terraform-provider-aws/issues/31384))
 * resource/aws_elasticache_replication_group: Update configurations to use `description` instead of the `replication_group_description` argument ([#31008](https://github.com/hashicorp/terraform-provider-aws/issues/31008))
