      The following description was in the original issue FAB-15779 which was used for testing this in v1.4.2. For this one in v2.0, we plan to use the operator function to help automate the migration steps when testing this in k8s lab.

      Create a network with 5 orderers, 5 kafka brokers, 3 zookeepers and 1 org with 1 peer

      Create 100 channels, join peer to channel, install and instantiate samplecc and start sending invokes

      While traffic is running, then migrate kafka to raft by following steps on orderer system channel and all 100 application channels:

      • Config update to change state from NORMAL to MAINTENANCE with kafka consensus type and leaving metadata to null
      • Config update with etcdraft as consensus type and raft metadata
      • Restart Ordering nodes and verify orderer logs for leader election
      • Config update to change state back to NORMAL from MAINTENANCE

      Once completed, verify the following:

      • Send new transactions to verify invokes and send queries on all 100 channels
