It looks you are trying to use the AWSSupport-MigrateEC2ClassicToVPC SSM runbook to migrate a "Paravirtual" Instance from EC2 classic to VPC.
Please note that AWSSupport-MigrateEC2ClassicToVPC SSM runbook only supports migrating Amazon EC2 instances of the hardware virtual machine (HVM) virtualization type with Amazon Elastic Block Store (Amazon EBS) root volumes. If you are still using "Paravirtual" virtualization type I would recommend to create an AMI of this instance and launch to a VPC by selecting your VPC under Network Settings.
Since "Paravirtual" virtualization type is old, I would also recommend to migrate to new HVM based virtualization to get good performance from our latest generation EC2 instance types. The official way to switch to an HVM instance is to create a new HVM instance, install your applications and then restore data from backups.
