● RDS Edition
Currently only MySQL 5.6 is supported: High Availability Changes
Only the following downgrade and upgrade scenarios are supported:If your RDS instance runs MySQL 5.6 on RDS Enterprise Edition, you can downgrade the RDS edition of the instance to the High-availability Edition.
● Instance Type
You can change the instance type of your RDS instance regardless of the instance configuration.
● Storage
All instances support increased storage space.
When only renewing the subscription and changing the configuration, the local disk-based annual and monthly subscription instance can reduce the storage space.
● Availability Zones
You can migrate an RDS for MySQL instance across zones within the same region. After the migration, the attributes, configuration, and endpoints of the instance remain unchanged.
● Network Type
All instances support private networks, and some instances also support classic networks. For instances that support both network types, you can switch network types.
● Payment Methods
Paid subcontracting yearly and monthly
● Region
The region of an instance cannot be changed. After you create an instance in the target region, you can migrate data through the data transfer service DTS, then modify the service connection address, and release the original instance after confirming that the service is normal.
