Q: How does Amazon RDS distinguish between “major” and “minor” versions of SQL Server?

In the context of RDS for SQL Server, version number is typically organized as follows:

SQL Server version = X.Y.Z.A.B

X = Major Database version, Z/A/B = Minor Version

For example, 13.00.2164.0.v1 to 13.00.4001.v1 would be a minor version upgrade while 12.00.5000.0.v1 -> 13.00.2164.0.v1 would be a major version upgrade

We follow Microsoft SQL Server conventions in our version names.

Q: Why can’t I scale my storage?

Your RDS for SQL Server instance may not be eligible for scaled storage. There are two main reasons why this may happen:
1. Magnetic Storage types aren't eligible.
2. Database instances launched before Jan 1, 2017 might be using an older storage configuration that isn't eligible.

Q: What can I do if my SQL Server instance isn't eligible for scaled storage?

You can migrate your existing instance to a new RDS for SQL Server instance, by taking a native backup or using a data migration tool. Make sure the storage type of the new instance is Provisioned IOPS or General Purpose (SSD).

Q: I just scaled my storage size. Can I do it again?

Yes. However, you will need to wait six hours from the previous scale.
