Hi I am trying to migrate data from a 3 node cluster to a new 5 node cluster. After completion of the migration I am seeing few additional records in new system. After analysis, I found that these records were already deleted in the source system just few days before the migration. It seems like the tomstones from source system are getting migrated to target system.
Please let me know if there is any way to avoid these tombstone rows. *Source System :* Cassandra 1.9.8 3 nodes Replication factor 1. *Target System :* Cassandra 2.0.2 5 nodes Replication factor 3. *Approach Followed for migration :* On each of the node from source cluster, flush data and generate snapshot. Move all the snapshots for all column families to new cluster. Run sstable loader for all the column families from one of the node from target cluster. Re-build indexes. Regards, LK
