Cassandra DSE to Cassandra DSC migration

votes

I have three nodes of Cassandra dse on three servers. I need to uninstall dse and install dsc, also I need to migrate the data from the dse cluster to dsc Cassandra cluster on the same servers.

What would be the best way to do it? Should I just install dsc and set the data folders in the configuration same as in the dse configuration?

Is there a better way?

  1. If you have less amount of data then first export data to CSV from DSE and import data from those CSV to DSC.

  2. If you have much data then use sstableloader here.

No because DSE has some special schema like dse_security etc ...

You can use Apache Spark to migrate quickly your data from DSE to DSC.
