Why Does Data Migration Fail?

Check if a master/standby switchover occurred during the migration. If it occurred, contact technical support to temporarily disable master/standby switchover until the migration completes.
For online migration, check whether the SYNC and PSYNC commands are disabled on the source Redis instance. If they are disabled, enable them to allow data synchronization.
To migrate data from a single-node or master/standby instance to a Proxy Cluster instance, check if any data exists in databases other than DB0 of the source instance. If yes, move the data to DB0. Otherwise, the migration fails.
A Proxy Cluster only has one DB, which is DB0.
