Resetting a Migration Task

During the migration, if a migration task fails due to uncertain causes, the background will resume the task several times. However, the task may fail to be recovered in some scenarios. To continue the migration, DRS allows you to reset the task.

You can reset the following DRS tasks:

MySQL->MySQL
MySQL->DDM
MySQL->GaussDB(for MySQL)
MySQL schema and logic table -> DDM
Redis->GeminiDB Redis
Redis Cluster -> GeminiDB Redis
MongoDB->DDS
DDS->MongoDB
GeminiDB Redis->Redis
GeminiDB Redis -> Redis Cluster

Method 2

On the Data Migration Management page, click the target task name in the Task Name/ID column.
