Can the configuration of a DM task be modified after it is created? For example, if I want to add a table for synchronization.

I saw other posts saying that the data source cannot be modified after creation and can only be deleted and recreated with the same name. Does the task need to be modified in the same way?

In TiDB’s data migration tool DM (Data Migration), once a data migration task is created, its configuration cannot be directly modified during runtime. This is because DM is designed to ensure the consistency and integrity of data migration. Once a task starts executing, any changes to the configuration could lead to unpredictable results.
