The primary database needs to be restarted, and the DM-master instance has been migrated. How can I export the configuration files of the already synchronized tasks?

A single dm-master? Expand first and then operate on this node.

Try this: dmctl --master-addr=<new_dm_master_address> dump-task <task_name> -s

The prompt says that dump-task is an invalid flag.
My version is 1.0, which is a relatively early version.
