Dear All,
I have a 13 Node cluster (15.07 version) which we'll be upgrading soon. We also aim to increase number of nodes Below is how we are aiming it:
1. We plan to create a 18 Node cluster.
2. Migrate the data (cassandra, ldap & postgres) from 13 Node to 18 Node.
3. Once testing is successful after data migration we will point our ELB's to 18 Node.
4. After monitoring for few days we will sunset our 13 Node servers.
Does anyone know how to migrate data from one cluster to another cluster ?
I've tried backup & restore and it's not working. I suspect backup and restore also restores UUID's hence it is creating issues.
I've also tried pg_dump for postgres but it was not working as well. Or maybe i didn't used it currently ???
Also we require steps for openldap.
Will be grateful if someone has tried it and can share the steps.
