Migrate RDS in us-east-1a

Question

I'm trying to migrate a PostgresQL 10 RDS DB to version 14. No matter which instance type I try, it says that it's not available in our availability zone (us-east-1a). Types we've tried:

db.r6g.large 
db.r6i.large
db.r5.large
db.t4g.xlarge
db.t3.xlarge
db.r5b.large
db.m6g.xlarge
db.x2g.large
db.m6i.xlarge

What can we do?

Best Regards,
Ortwin

Accepted Answer

All newer instance types are VPC only. The reason for this issue is that your instance is using Classic networking. You need to first move your instance into a VPC in order to use current instance types.
