Description
You can call this operation to change the type of an AnalyticDB for PostgreSQL instance.
Note
- The instance must be in the running state when you change the type. Otherwise, the operation fails.
- Instance type upgrade takes about 30 minutes to 3 hours to complete. The times varies with the data volume of the instance.
- To ensure data consistency, the instance only provides the read-only service during the change process, and the instance will have two transient disconnections. We recommend that you arrange your business in advance to avoid service interruptions.
- After the type is changed, the database kernel of the instance is automatically upgraded to the latest version.
For more information about how to perform the corresponding operation in the console, see Upgrade the instance configuration
