Take over OBSharding

This topic describes how to take over OBSharding in the OceanBase Admin Toolkit (OAT) console. Earlier versions of OAT cannot be smoothly upgraded to the current version because the new version has been restructured. Therefore, the current version of OAT must take over the products and components deployed by using earlier versions of OAT to monitor their status and manage their upgrades.
