Description

The Change RDS Instance Class action can be used to change the class (or machine size) of a running RDS instance. Later, it can (optionally) be changed back.

For example, at 8am, a micro (db.t1.micro) instance can be upgraded to a large instance type (db.m1.large), then 8 hours later, it can be reverted back to it's original size (db.t1.micro).

Important Note

The process of changing an RDS instance's class requires the instance to be offline briefly while the modification occurs.

Settings

Please see Common Action Settings for a description of settings common to all action types.

Indicate the instance identifier of your RDS instance. This instance must reside in the region specified.

Revert the Instance Class

Indicate whether the instance class should be automatically reverted later. The running time of the instance must also be specified if this is enabled.
