Cannot upgrade DB Engine (from Express to Enterprise Edition) when restoring a SQL Server snapshot

Occasionally the RDS console might show unexpected behavior. However, the APIs remain the same.

You can always use the AWS CLI to perform the same when the console is acting up.

The command below works for me.

aws rds restore-db-instance-from-db-snapshot --db-instance-identifier new-ent --db-snapshot-identifier sql-express --db-instance-class db.m5.xlarge --engine sqlserver-ee --no-multi-az --no-publicly-accessible --region us-east-1 --output json
