How can i be sure i'm using EC2-VPC and not EC2-Classic?

Question

I'm using an old account but i'm a beginner at AWS so i need some help to make sure im using VPC and not Classic so i don't lose my instances when they retire classic. I've read other topics that say that if an instance has VPC-ID defined it means that it's on a VPC, but i just want to make sure. I have 5 instances, 4 of them have VPC-ID: VPC name, but there's an old instance that's like this:VPC-ID: - Does this VPC-ID thing work for RDS too? Meaning if it's defined, it's in a VPC? But apart from that, is there any other way to make sure they're already in a VPC and won't be deleted?
I created the instances and rds's last year
(I tried using the script but it's too complicated to do with my current knowledge)

Thank you for your help and patience

AWS is already notifying the remaining EC2-Classic customers via their account teams, and will soon start to issue notices in the Personal Health Dashboard.

All AWS accounts created after December 4, 2013 are already VPC-only, unless EC2-Classic was enabled as a result of a support request.

Refer section, "Finding EC2-Classic Resources" in the below mentioned blog and you ll be able to find anything related to EC2-classic in the account. Use the same and migrate the EC2- classic to VPC.

Hope this helps. If it did, please click on accepted answer.
