Lifecycle Rules: - Add prevent_destroy = true to all 32+ resources - Add ignore_changes = [tags] to prevent tag drift from causing recreation - Add ignore_changes = [tags, user_data, ami, iam_instance_profile] for EC2 - Preserve existing create_before_destroy for security groups and ACM Import Blocks (orphaned resources): - Lambda: sacc4-stop-instances - Lambda: sacc4-start-instances - EventBridge: sacc4-stop-instances-schedule - EventBridge: sacc4-start-instances-schedule Data Sources: - aws_instances.existing_api (detect EC2 duplicates) - aws_db_instance.existing (detect RDS duplicates) - aws_nat_gateways.existing (detect NAT GW duplicates) - aws_cloudfront_distribution.existing (detect CloudFront duplicates) Variables: - db_identifier: for RDS duplicate detection - cloudfront_distribution_id: for CloudFront duplicate detection Validation Results: - terraform validate: PASSED - terraform plan: 0 to add, 1 to change, 0 to destroy - No resources marked for recreation Orphan EIP detected: - eipalloc-0bdf9c47a80885c7a (78.13.177.201) unattached - Requires manual cleanup or investigation Refs: AWS Resource Validation - May 2026
