Hello Team,

Please help, How can we migrate multiple tables from a Keyspace at the same time using the Scylla migration tool?
I tried making changes to config.yml, but it did not work.

error:
Exception in thread “main” DecodingFailure(Attempt to decode value on failed cursor, List(DownField(table), DownField(source)))

hi there,

Could you show us what your config.yaml looks like?
