New AWS resource groups collect references to relevant AWS account resources in one place (per Cornell AWS account) for easy reference and review:
Resources can and will appear in multiple resource groups!
- cit-dc-arch-migration-affected-resources – These resources will be directly affected by this migration. These resources include:
- new resources that support the v2 architecture
- resources that support the v1 architecture and will no longer be needed for the v2 architecture
- resources that will remain, but will have their configuration changed to support the v2 architecture
- Transit Gateway Attachments should appear in this list, but a limitation of AWS Resource Groups appears to exclude these resources.
- cit-dc-arch-version-1-resources – All network resources that support or utilize the v1 architecture
- cit-dc-arch-version-2-resources – All newly-created resources that support the v2 architecture Transit Gateway Attachments should appear in this list, but a limitation of AWS Resource Groups appears to exclude these resources.
After the v1 → v2 migration is complete, v1 resources will either be deleted (if they are not used in the v2 architecture) or relabeled as v2 resources (if they continue to be used in the v2 architecture).
These Resource Groups will be created during the Preparation phase of the migration. See Migration Process.

Route Tables
The AWS Transit Gateways used in the v2 architecture require different routing rules than the Virtual Private Gateways (VGW) used in the v1 architecture. Each VPC Route Table that references a Virtual Private Gateway will be duplicated and, in the new Route Table, rules referencing a VGW will be replaced with rules referencing a TGW Attachment.
