Data continuously writing in to cassandra.
As per the above step i starts to migrate cassandra from initial token to
virtual node. But in between i found data ( Data which added after rebuild) is
unavailable from new data center.
After rebuild i update keys
>From new data center unavailability start from rebuild nodes in new data
