Migration from solo consensus to raft consensus

发布于 2020-04-23 11:16:43

I've used byfn.sh to build a hyperledger network with solo consensus.

Now I want to migrate to Raft consensus, but without destroying the blockchain and start from zero.

Is it possible to migrate Hyperledger fabric from Solo consensus to Raft consensus ?

Thank you in advance.

Yes, it's possible and it's basically very similar to the Kafka to Raft migration. Take a look at the Kafka to Raft migration guide and follow it

Thank you. Excuse me if this sound like a stupid question. So I should fire up 4 new orderers and proceed to migrate from solo to RAFT ?

Keep in mind that if you do that, every orderer that you add must be added to all channels, otherwise you're stuck. Look at jira.hyperledger.org/browse/FAB-17479 for more details
