Take over OMS

This topic describes how to take over OceanBase Migration Service (OMS) 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.

Prerequisites

Before you take over OMS, make sure that the following conditions are met:

• You have added the image used by OMS.

• You have taken over the components that OMS depends on.
