Tama MA commented on KAFKA-14341:
---------------------------------
It turns out that we have to remove the old Kafka data folder - and bootstrap
now works OK.
[~ijuma] - FYI
[~cmccabe] Hi, I saw that you are active contributor - KIP-801. Thank you! I
would like to indicate that your PR works OK for a clean instance bootstrapped
from scratch. Migrating from old KRaft is not OK for me. However, as I use
Kafka mainly as retention buffer, so removing the old instance is ok for me
privately.
Enterprise-wise, deleting an old volume would require a lot of management
approvals ... nonetheless, it works - and thank you!
