How to Resolve Manually

You might think, how can I create an Amazon EC2 Instance outside of a VPC? Years ago, this was possible and you might have some EC2-Classic style instances such as m1 family instances which could have been created outside of an Amazon VPC.

Lately, it is not possible to launch an Amazon EC2 Instance into an Amazon Virtual Private Cloud (VPC)

If you still have old EC2 Instances that need to be moved within an Amazon VPC you own however, you can make use of the AWS Application and Migration Service (AWS MGN) to migrate your instances (and/or databases) from EC2-Classic to VPC with minimal downtime.

Note: EC2-Classic is scheduled to be retired on August 15, 2022
