I would like to ask how to downgrade DM. After upgrading from version 5.2 to 5.4, I found that when reading binlog logs, table names and field names are enclosed in double quotes, causing DM synchronization exceptions. This issue did not exist in version 5.2, and I also enabled case-insensitive configuration during the upgrade. So frustrating~~~~

tiup does not support downgrading. You can only scale down, manually clean up the directory information, and then scale up again.

The PR seems to have been inactive.

Currently not supported. As for case-sensitive configuration, it needs to be configured in the task YAML file. Just refer to the DM documentation more.
