Release notes

The following release notes cover the latest changes to AWS Transform for migrations, including Migrations (including VMware) and Migration assessments. For a list of changes across the full AWS Transform service, see the changelog.

For supported AWS Transform regions, see Supported Regions. For supported target regions, see the account connector setup page.

November 2026

October 2026

  • AWS Transform network migration can now generate your network, or the security groups for your existing VPCs, from your migration plan data, so you no longer need to upload a separate network file. AWS Transform uses your server and application inventories and the network connections observed during discovery and migration planning. Learn more about using migration plan data as network input.

  • AWS Transform network migration now supports designing a new AWS network from your requirements, in addition to importing a source network and applying source security rules to existing VPCs. AWS Transform helps you select a topology, sizes your VPCs, and generates a production-ready network that follows AWS best practices, which you review before deployment. Learn more about designing a new AWS network.

  • AWS Transform landing zone capability now supports connecting through a Delegated Administrator account, allowing organizations with strict governance policies to use AWS Transform without granting direct access to the management account. When using a Delegated Administrator connector, the capability operates in IaC-only mode, generating Infrastructure as Code artifacts (CDK, Terraform, or Landing Zone Accelerator format) for your own deployment pipeline instead of directly provisioning resources. This provides flexibility for organizations that prefer to manage landing zone changes through existing deployment processes. Learn more about connector setup and IaC-only mode.

  • AWS Transform migration assessments now assess on-premises storage for migration to Amazon S3, Amazon EBS, and Amazon FSx for NetApp ONTAP. Upload a storage inventory, such as an RVTools export, and AWS Transform maps each workload to one of these services, sizes it, and estimates its cost, including Single-AZ and Multi-AZ pricing for Amazon FSx for NetApp ONTAP. Learn more about storage assessments.

September 2026

  • AWS Transform landing zone capability now supports additional brownfield scenarios, including existing AWS Control Tower landing zones and landing zones built with AWS Organizations. You can run a foundation gap analysis and expand your landing zone on top of the existing landing zone in your target account. Learn more about foundation discovery and planning.

  • AWS Transform migration assessments now assess self-managed Apache Kafka clusters for migration to Amazon MSK Express. AWS Transform recommends a broker configuration and estimates the total cost of ownership across broker hours, storage, data-in, and cross-Availability Zone transfer, along with a compatibility review of the source cluster. Learn more about analytics assessments.

  • AWS Transform migration assessments now include Compute Savings Plans and Amazon EC2 Instance Savings Plans as pricing options for Amazon EC2 recommendations, alongside On-Demand and Reserved Instances, so you can compare committed-use discounts in your migration business case. Learn more about compute assessments.

August 2026

  • AWS Transform for migrations now lets you refine the generated AWS security groups while reviewing your target network. You can create, configure, and delete security groups and their rules. You can also associate a rule with a CIDR range or a source , and enable security group referencing for a specific rule. Learn more about reviewing and optimizing your network.

  • AWS Transform for migrations now supports for as a generally available block storage target, alongside Amazon EBS. You can migrate block storage directly to for within the same migration wave that handles compute and networks. Learn more about configuring for as a target storage type.

  • AWS Transform for migrations now lets you apply your source security posture to Amazon VPCs you have already provisioned in AWS, instead of creating new Amazon VPCs. You upload a source network file that contains firewall rules, tag the existing Amazon VPCs you want in scope, and AWS Transform matches your source subnets to those Amazon VPCs by and generates the corresponding security groups. Learn more about applying security posture to existing Amazon VPCs.

  • AWS Transform for migrations now identifies unused inbound firewall rules migrated from your on-premises environment and suggests removing them as part of guided network recommendations. This helps you avoid carrying forward security exposure, such as open inbound access, that no longer serves a purpose. Removal is limited to unused ingress rules. Learn more about guided network recommendations.

  • AWS Transform for migrations now flags Amazon VPCs that host applications from multiple environments, such as development and production, as part of guided network recommendations. When the environments can be cleanly separated, AWS Transform suggests splitting the Amazon VPC to isolate them. Learn more about guided network recommendations.

  • AWS Transform for rehost now allows you to modify server configurations through the chat interface during the inventory validation step. In addition to editing the inventory file directly, you can specify changes for individual columns on specific source servers without downloading and editing the entire inventory file. This provides a more convenient way to make targeted updates to your server configurations. Learn more about inventory validation and modifications.

July 2026

  • AWS Transform for migrations now offers expert mode, which lets you provide your inputs up front so the agent completes migration steps automatically with minimal back-and-forth. This helps you move faster through large migrations while keeping control of the decisions that matter. Learn more about expert mode.

  • AWS Transform for migrations now supports migrating virtual and bare metal server environments from virtually any source, including VMware, Hyper-V, and other platforms. Migration capabilities, including discovery, migration planning, landing zone creation, network migration, and server rehost, are available regardless of your source infrastructure. The web application workflow has been renamed from "VMware Migrations" to "Migrations (including VMware)". Learn more about migrations.

  • AWS Transform now lets you generate a workspace summary report as a downloadable PDF. The report consolidates data from all migration jobs in your workspace, including job statuses, workflow step progress, wave planning, network migration, landing zone configuration, rehost progress, and artifacts produced. Learn more about workspace summary reports.

  • The AWS Transform discovery tool now collects detailed Oracle metadata directly from your databases across VMware, Hyper-V, and bare metal servers. You can discover Oracle instances through direct SQL connections. The tool collects Container Database/Pluggable Database (CDB/PDB) enumeration, component inventory, and datafile sizing. Learn more about Oracle Database discovery.

  • AWS Transform for migrations now provides enhanced capabilities for post-launch actions. You can now define post-launch actions at the account level and apply them to all source servers automatically, or customize them per source server during inventory validation. Post-launch actions automate modernization and validation tasks on each source server immediately after it launches as a test or cutover instance. Learn more about post-launch actions.

June 2026

  • AWS Transform for migrations now supports localization. You can change the display language of the web application when working with migration workflows. Learn more about language settings.

  • AWS Transform now allows you to configure your replication settings and launch settings for your migration. You can set the configuration per your target account or across specific source servers. Learn more about replication and launch settings.

  • AWS Transform now allows you to attach existing Elastic Network Interfaces (ENIs) to your launch template. You can tag ENIs in your target account so they are available for use when instances are launched. Learn more about network resource tagging.

  • AWS Transform for migrations now supports all AWS commercial regions as migration targets, excluding Middle East (Bahrain) and Middle East (UAE). Learn more about supported target regions.

  • You can now use the AWS Transform discovery tool as a source for network migration alongside modelizeIT, enabling hybrid network migrations for environments running both VMware and non-VMware workloads. Learn more about network migration input sources.

May 2026

  • AWS Transform now detects existing VPCs in your target account during network migration review. You can see existing VPCs alongside your mapped VPCs, identify CIDR conflicts, and resolve them before deployment. Learn more about existing VPC detection.

  • AWS Transform supports replatforming source code repositories to containers during migration to AWS. Learn more about containerization.

  • AWS Transform can now analyze your discovered inventory and provide a migration strategy recommendation for every server and application. Recommendations follow the industry-standard seven migration strategies (7Rs). Each recommendation includes a suggested AWS target service, a confidence score, and the reasoning behind it. Learn more about 7Rs recommendations.

April 2026

  • Added landing zone creation directly within migration workflows. AWS Transform checks for an existing foundation, recommends Organizational Unit (OU) structures and target accounts, and offers automated deployment or Infrastructure as Code (IaC) output (CloudFormation, AWS CDK, or Landing Zone Accelerator (LZA) formats). Learn more about landing zone creation.

  • Added support for DHCP with security group mapping during network migration. Learn more about security group creation.

  • You can now generate interactive diagrams and analytical reports during migration planning. Diagram types include network topology maps, application dependency graphs, wave Gantt charts, and general charts. Report types include risk assessments, 7Rs recommendations, and custom analytical reports. Outputs are available as interactive HTML, PDF, or Microsoft PowerPoint (.pptx) files. Learn more about migration-planning diagrams and reports.

March 2026

  • Added public APIs for network migration, enabling partner and programmatic access to network migration capabilities. See the network migration API reference.
