I advise to do it non-prod for validation .
You can backup data log folder if you want but I have'nt see any issue . but
better to backup data if it small .
Don’t change below value to latest until you done full validation , once you
changed to latest then you can't rollback .
inter.broker.protocol.version=2.1.x

Thanks Manoj! Appreciate your help..
I will follow the steps you pointed out..
Do you think there is a need to :
1. backup the data before the rolling upgrade
2. some kind of datasync that should be considered here.. I don't think
this is required as I am performing an in-place upgrade..
Thanks & Regards,
Rijo Roy
