"it seems that we still need to keep bootstrap false?" Could you shed some light on what would happen if the auto_bootstrap is removed (or set to true as the default value) in the seed nodes of the newly added DC?
What do you have in the seeds param of the new DC nodes (cassandra.yaml)? Do you reference the old DC seed nodes there as well?

Most of my colleagues miss very important steps while adding/removing nodes/cluster, but if they stick to the docs, they always get it done right.
