 We decided not to add this for now as there are no requirements for any routing from live-2 VPC to the MoJ Transition Gateway. Also live-2 is planned for decommission.
 If there is a requirement for this, the [add-live-2-tgw-routes branch] shows the code that needs to be applied.
 
-## Moving away from the *old* Cloud Platform Transit Gateway account
-`Cloud Platform Transit Gateway` AWS account and [transit-gateways repo] previosuly held the terraform state in s3 bucket and terrform code respectively. We have migrated this to the `Cloud-Platform` AWS account and [cloud-platform-infrastructure] repo now. The following tasks remain to completely decommision the old Cloud Platform Transit Gateway:
-
-- Confirm with owners of Transit Gateway VPC Attachments in Cloud Platform Transit Gateways AWS account can be deleted
-- Confirm with owners of Transit Gateway Peering Attachment in Cloud Platform Transit Gateways AWS account can be deleted
-- Terraform destroy all redundant Transit Gateway related resources in Cloud Platform Transit Gateways AWS account that are currently being managed by terraform.
-- Remove redundant code from [transit-gateways repo]
