【TiDB Usage Environment】Production Environment
【TiDB Version】Old V5.2.1 New V6.2.1
【Encountered Issues】1. Currently, we need to migrate full data between two clusters. Will there be compatibility issues with versions when using BR for data migration? 2. What methods can be used to avoid this, or what other methods can be used for migration?

DM is used to migrate from databases compatible with the MySQL protocol to TiDB. Can it perform a full migration between two TiDB clusters?

I just saw that you can use dumpling to export data and then use lightning to import data. Thank you for your attention.
