Associating Option Group with exisiting RDS instance

Question

I have an existing MSSQL 12 Express RDS instance. I want to enable native restore and backup for this instance. Following the official documentation I created an Option Group. How can I associate this Option Group with my RDS instance using the web interface.

Answer 1

In the list of RDS instances in the web console you select the instance, and then click Instance Actions -> Modify. In the modification page you can change the assigned Option Group among many other things.

Make sure you click "Apply Immediately" at the bottom of that page if you want the changes to take effect immediately, instead of waiting until the next maintenance window.
