Hello, newbie here. Currently we are using Cassandra v2.2.1 (two DCs, naming them DC1, DC2, respectively), and recently we have two issues:
1. Cannot adding new node due to CASSANDRA-10961 2. Cannot repair node, due to CASSANDRA-10501 We learned that we can do rolling upgrade, since we are only using one DC1 for now (DC2 is just for replica), we have following steps in mind: 1. Backup; 2. Doing upgrade on DC2. (Follows this guide: https://docs.datastax.com/en/latest-upgrade/upgrade/cassandra/upgrdCassandraDetails.html ); 3. Do some checks (client compatibility, etc); 4. Adding nodes to DC2 (using new Cassandra); 5. Traffic our loads to DC2; 6. Upgrading DC1. Is that possible, or do we miss something? Thanks in advance! Timon
