 * data-source/aws_iam_policy_document: `source_json` and `override_json` have been removed -- use `source_policy_documents` and `override_policy_documents`, respectively, instead ([#30829](https://github.com/hashicorp/terraform-provider-aws/issues/30829))
 * resource/aws_autoscaling_attachment: `alb_target_group_arn` has been removed -- use `lb_target_group_arn` instead ([#30828](https://github.com/hashicorp/terraform-provider-aws/issues/30828))
+* resource/aws_route: `instance_id` can no longer be set in configurations. Use `network_interface_id` instead, for example, setting `network_interface_id` to `aws_instance.test.primary_network_interface_id`. ([#30804](https://github.com/hashicorp/terraform-provider-aws/issues/30804))
+* resource/aws_route_table: `route.*.instance_id` can no longer be set in configurations. Use `route.*.network_interface_id` instead, for example, setting `network_interface_id` to `aws_instance.test.primary_network_interface_id`.

 NOTES:
 
 * 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))
