AWS Transform Covers Schema to Cutover
Offline SQL Server schema conversion, SSM post-launch actions and continuous modernization GA in one week, plus Lambda bandwidth and Aurora Serverless scaling.

In the first week of August, AWS Transform shipped three launches that together cover a migration from the schema you have not converted yet to the technical debt you will find a year after cutover. On 3 August the Windows modernization agent gained offline SQL Server to Aurora PostgreSQL schema transformation and continuous modernization went generally available; on 6 August the migration workflow learned to run post-launch actions through Systems Manager. Around it, Lambda got up to 3,000 Mbps of network bandwidth, Aurora Serverless learned to jump to 12 ACUs in a second, and the load balancers picked up NSA-grade TLS policies.
The thesis for the week: AWS is no longer selling Transform as a rehost tool with an AI label. It is filling in the parts of a migration that used to be a partner's spreadsheet, and that changes what you should expect to do by hand.
AWS Transform: schema, cutover, and the year after
Take the three in migration order. The offline schema transformation accepts SQL Server DDL files, so you do not need a live connection to the source. It assesses database and stored procedure complexity, lets you edit the generated plan, then converts tables, schemas, stored procedures and functions, validates functional equivalence, and deploys the result to Aurora PostgreSQL. Storage object conversion is powered by AWS DMS under the hood. It is US East (N. Virginia) only for now. The offline part matters more than it sounds: the teams that cannot start a database migration are usually the ones whose DBAs will not open a port to a conversion tool. A DDL dump is an easier conversation.
Post-launch actions close the gap between "the server booted in AWS" and "the server is actually ours". You define actions once at the account level, and Transform applies them to every source server, across target accounts in a multi-account migration, running them through AWS Systems Manager right after a test or cutover launch. Predefined actions or your own SSM document. The migration inventory file also gets a structure for per-server review. If you have run MGN at scale, you know the failure mode this removes: a wave of 80 servers lands and someone runs the CloudWatch agent install by hand on 79 of them.
Continuous modernization is the piece aimed at what happens after. It connects to GitHub organizations, GitLab groups and Bitbucket workspaces, runs on demand or on a schedule, ranks findings by technical debt, security, agentic readiness and modernization readiness, and for findings with a fix it opens pull or merge requests with validated changes. The analysis runs in your own account under your credentials, and you can drive it from the web app, the CLI, Kiro, or as an agent plugin. The trade-off is the same one every automated PR tool carries: review capacity. A scheduled scanner that opens PRs faster than the team can read them becomes noise within a quarter. Start with one repository group and a strict rank filter.
Lambda bandwidth: 3,000 Mbps, if you are not in a VPC
Lambda network bandwidth now scales with memory for functions with 2 GB or more, from 625 Mbps at 2 GB to 3,000 Mbps at 10 GB, replacing the flat 625 Mbps ceiling. No extra charge, all commercial Regions. Two caveats carry the launch. First, it is opt-in via a Service Quotas request on the "Network bandwidth per execution environment" quota, after which every non-VPC function in the account scales automatically. Second, and more important, it applies only to functions outside a VPC. Most enterprise functions that move large objects are inside one, because that is where the RDS instance and the private S3 endpoint live. If your heavy S3-to-S3 transforms run in a VPC, this week changed nothing for you. Check with aws lambda get-function-configuration --function-name X --query VpcConfig before you file the quota request.
Aurora Serverless: 12 ACUs in a second
Aurora Serverless now reaches up to 12 ACUs within a second during scale-up, continues to 256, and still scales to zero afterwards. It is on by default for clusters on platform version 3 or 4; versions 1 and 2 can upgrade directly to 4. Check yours with the ServerlessV2PlatformVersion field from describe-db-clusters. AWS frames this around agentic workloads, which is fair: an agent fan-out is exactly the burst that used to spend its first 30 seconds waiting for capacity. The failure mode is cost. A cluster that previously ramped gently now hits 12 ACUs on a spike that would have been absorbed at 2. Put a CloudWatch alarm on ServerlessDatabaseCapacity before you upgrade the platform version, not after the first bill.
Also this week
- ALB and NLB gained TLS security policies aligned with RFC 9151 (NSA CNSA 1.0) for TLS 1.2 and 1.3, with interoperability variants so you can default to CNSA while still serving older clients during a migration.
- Network Firewall explicit forward proxy returned in preview in US East (Ohio), this time sharing the firewall's own policy instead of the separate proxy policy from the November 2025 attempt.
- OpenSearch Service extended patch coverage for Elasticsearch 1.5 to 7.8 and OpenSearch 1.0 to 2.9 until 7 November 2027, but from 7 November 2026 the Extended Support surcharge equals your instance price.
- Security Hub Extended added supply chain security as its tenth category, with Chainguard and Socket as the curated partners.
- VPC IPAM added BGP route protection monitoring and delegated RPKI for BYOIP prefixes, creating and renewing ROAs for you after a one-time RIR setup.
- IAM Identity Center made AWS account access optional for new organization instances, so an application-only instance no longer deploys its service-linked role into every member account.
- AWS Backup for S3 lets you read backup data through an S3 Access Point with
GetObjectandListObjectsV2, no restore job required. - ECR raised the maximum image layer size to 200 GB for Docker pushes;
UploadLayerPartthrough the SDK or CLI stays at 50 GB. - Lambda Provisioned Mode for SQS went to 10,000 event pollers, up from 2,000, or 100,000 concurrent invocations per mapping.
- ECS schedules fractional GPUs on G6f instances: set
GPUto 0.125, 0.25 or 0.5 in the container definition. - AI corner: DynamoDB vector search went GA, AgentCore runtime instances let agents run on your own EC2 capacity with 14-day sessions, and Web Search on Bedrock went GA for OpenAI models. The agent side of that is covered at ercan.ai.
The throughline
Read the Transform launches next to the Lambda and Aurora ones and the pattern is about where the manual work was hiding. Schema conversion hid behind a firewall rule nobody would approve. Post-launch configuration hid in a runbook. Technical debt hid in the backlog. Lambda's bandwidth ceiling hid behind a quota, and Aurora's ramp hid in the first 30 seconds of every spike. AWS spent the week removing hiding places. The cost of that is the same every time: the defaults get more aggressive, and the platform team has to decide, up front, which of those defaults it actually wants.
