Hi,
I am a newbie in Kafka and would greatly appreciate if someone could help
with best-practices and steps to upgrade to v5.3x.
Below is my existing set-up:
OS version: Ubuntu 16.04.6 LTS
ZooKeeper version : 3.4.10
Kafka version : confluent-kafka-2.11 / 1.1.1-cp2 / v4.1.1
We need to upgrade our OS version to Ubuntu 18.04 LTS whose minimum
requirement is to upgrade Kafka to v5.3x. Could someone please help me with the
best-practices & steps for the upgrade..
Please let me know if you need any more information so that you could help
me.
Appreciate your help!
Thanks & Regards,
Rijo Roy
