ARetry the migration from Kafka to Raft.

BRestore the state from a backup.

CRevert to the previous version of Kafka.

DRebuild the network from scratch.

Show Suggested Answer

Suggested Answer: B

Recovering from a failed migration from Kafka to Raft in Hyperledger Fabric involves restoring the state from a backup. This is necessary because once the ordering service is migrated to Raft and begins committing transactions, reverting to Kafka is not supported without a previous backup. If a migration is botched, and a backup was made at the appropriate point, administrators can roll back to this backup to restore the system to its pre-migration state .

B) Restore the state from a backup. Duh, that's the textbook answer. Unless you want to start from scratch and build a whole new Kafka cluster.

Hold on, are we sure there's no cheat code or secret handshake to recover from this? Just asking for a friend.

I would go with option B as well, it's better to have a backup plan in case of failure.

I agree with Janella, restoring from a backup seems like the safest option.
