Function

This API is used to perform batch pre-check to check whether the migration, synchronization, DR can be performed.

Constraints

After a task is created, the task status is CONFIGURATION. The task can be invoked only after the test of connections to the source and destination databases is successful and the API for modifying the task is invoked.
In the dual-active DR scenario, when the forward task status is INCRE_TRANSFER_STARTED, the backward task does not need to call this API, and the parent task cannot call this API.
