Re: solo to kafka

Dear Artem,

Seems that migration from solo to kafka is impossible but solo to raft it's possible in v1.4. Have you some documentation about this? Can you give me some links or books?

Change from solo to raft permit me to have

Best regards.

No, this is not that I've said. I told that there is no way to migrate from Solo to Kafka ordering service and there no one should use Solo for production. Changing orderer type from Solo to Kafka simply not supported, however your Solo ledger will remain as-is.

Dear Artem Barger,
You say me that if i change orderer i lost all the transaction in my ledger?
There is no way to mantain the transactions?
Thanks for your answer.
