@vishnuvardhanp4 If you just upgrade the broker, I think this will not lose any data. If you want to upgrade the bookkeeper too, you can do like followings: 1. Disable the auto-recovery to prevent the not necessary data replication during the bookkeeper upgrade.(`bin/bookkeeper shell autorecovery -disable`) 2. Upgrade the bookies one by one(after one upgraded, check the bookies works as expected, can write data and read data) 3. After all bookies upgraded, enabled the auto-recovery(`bin/bookkeeper shell autorecovery -enable`) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
