AWS Transform now modernizes networks during migrations

Network migration teams previously spent days manually reviewing network designs and discovered conflicts only at deployment. AWS Transform now includes two new capabilities that solve both. A new modernization engine goes beyond network mapping to optimize constructs across naming, sizing, security, and structure while surfacing conflicts with existing VPCs already deployed in target accounts. It replaces days of manual review with instant guidance before a single resource provisions in AWS. The service also accepts network configuration files in any format, processing them for migration regardless of source tool or vendor.
Before provisioning begins, network teams review and act on modernization recommendations directly or edit any mapped VPC or subnet, retaining full control over the final network design. AWS Transform recommendations include:

• Splitting VPCs with mixed workload tiers into segmented environments
• Consolidating constructs fragmented by on-premises hardware constraints
• Right-sizing CIDR allocations to eliminate waste and improve address space management
• Standardizing naming conventions across all constructs
• Flagging unrestricted security group rules that pose security risks
• Removing out-of-scope resources from the target environment
• Identifying CIDR conflicts between mapped and existing VPCs across target accounts, recommending resolutions, and implementing the customer's chosen path

Customers can now upload their network configuration files as-is, and AWS Transform translates them into AWS-compatible networks. Customers reach deployment faster, as they optimized their network, resolved conflicts, and made every decision themselves.

These features are available in all AWS Transform Target Regions.
