Services will be interrupted for 5 to 10 minutes when you change DB instance specifications. Exercise caution when performing this operation.

Constraints

The instance specifications can be modified only for DB instances in the Available status.
The specifications of a DB instance can be changed only to the specifications of the same DB instance type. (For example, the specifications of a single-node instance cannot be changed to those of primary/standby instances.)
