Anything wrt statistics/cache ?
Your time and responses on this are much appreciated.

online migration? - I still need to
get clarity on whether data for same keyspace/table names can be merged
between A and B. So 2 cases - 1. If merge is not an issue - I guess DSBulk
or SSTableloader would be an option? 2. If merge is an issue - I am
guessing without app code change - this wont be pos
have fresh data.

Cassandra Version - Cassandra 3.0.13 on both sides.
Total Data size - Cluster A: 70 GB, Cluster B: 15 GB

Thanks Paul. This is interesting.
So, anything I need to do after cp? - nodetool repair?
Also I am assuming I need to be doing this exercise on all the nodes of the
cluster - right?
Any suggestion to automate this or do it just from a single node?

Thanks folks for your responses but still haven't found concrete solution
for this.

Thanks Paul.
Copy SSTable - How? Using SSTableLoader or some other mechanism.

Thanks Alex. So How do I copy SSTables from 1.0 to 2.0? (Same SSTableLoader
or any other approach?)
Also since I've multi-node cluster - I'll have to do this on every single
node - is there any tool or better way to execute this just from a single
node?
*Thanks & Regards,*
*Ankit
time
consuming, also being a multi-node cluster (6+6 in each DC) - it wouldn't
be very feasible to do this manually on all the nodes for multiple tables
part of that keyspace. Was wondering if we have any other creative way to
suffice this requirement.
Appreciate your time on this.
