Take over OB Sharding

This topic describes how to take over OB Sharding in the OceanBase Admin Toolkit (OAT) console. OAT of earlier versions cannot be smoothly upgraded to the new version because the new version has been restructured. Therefore, you must use OAT of the new version to take over the services and components deployed by using OAT of earlier versions. This way, you can monitor the status of the services and components and manage their upgrades.
