So, sstableloader streams a portion of data stored in
/var/lib/cassandra/data/keyspace/table catalog
If we have 3 nodes and RF=3, then only 1/3 of data would be streamed to
other cluster.
Problem is solved.

We have a "red team" and a "blue team in each AWS region, so we just add

Pretty simple."

IMHO, the most straight forward solution is to add cluster2 as a new DC for
mykeyspace and then drop the old DC.
That's how we migrated to VPC (AWS) and we love this approach since you
don't have to mess with your existing cluster, plus sync is made
automatically and you can then drop your old DC
>I have to ask you if you considered doing an Alter keyspace, change RF
The idea is dead simple:
get data from cluster1,
put it to cluster2
vipe cluster1
I understand drawbacks of streaming sstableloader approach, I need right
now something easy. Later we consider switch to Priam since it does

Hi,
Despite of "I understand that it's not the best solution, I need it for
testing purposes", I have to ask you if you considered doing an Alter
keyspace, change RF > 1 for mykeyspace on cluster2 and "nodetool rebuild"
to add a new DC (your cluster2) ?
In the case you go your way (sstableloader)
