I know it is possible to "Move to VPC Scope", but is it also possible to move back from VPC to Classic EC2?
1 Answer
No.
Classic EC2 goes away entirely in 11 days, and it hasn't been possible to create a classic version account since 2013.

We are retiring EC2-Classic on August 15, 2022. We recommend that you migrate from EC2-Classic to a VPC.

On August 15, 2022 we expect all migrations to be complete, with no remaining EC2-Classic resources present in any AWS account.
You can do anything you could do in classic within a VPC.
