ApsaraDB for MongoDB:Update the minor version of an instance

Usage notes

• You cannot downgrade the minor version after an update.

• A minor version update restarts the instance and causes a connection interruption of up to 30 seconds. Perform this operation during off-peak hours, or ensure your application supports automatic reconnection.

• The system may automatically update the minor version during the following operations if your instance is not already on the latest version.

  Actions	Description
  Upgrade the major version of an instance	Both cloud disk edition and local disk edition instances are updated to the latest minor version.
  Restart an instance or its components	Both cloud disk edition and local disk edition instances are updated to the latest minor version. Important Restarting a node does not update the minor version.
  Migrate data	If the migration target is a new instance, the new instance runs the latest minor version by default.
  Change the configurations of an instance	Only local disk edition instances are updated to the latest minor version. Important Changing only the storage capacity does not trigger a minor version update.
