Scenarios

If you use RDS for a long time, you can change the billing mode of one or multiple DB instances from pay-per-use to yearly/monthly at a time for a lower tariff.

• Read replicas do not support changing the billing modes from pay-per-use to yearly/monthly.
• Pay-per-use DB instances in any of the following statuses cannot be changed to yearly/monthly: frozen, creation failed, changing instance class, and scaling up.
