Changing consumer group in live

Hello,

Let us consider one application in a consumer group consuming events from
Kafka in live. Just like any code change, I changed the consumer group name
of the application to a new group. I understand my application might start
reading from the beginning offset or the latest based on the setting. Is
there any under-the hood problem for the application or the earlier
consumer group for doing the change? Any resource to read about it?

Thanks
