Upgrading from 0.11.0.2 to 2.2.1

[Vincent Rischmann <vi...@rischmann.fr>]

Hello,

I have a cluster still on 0.11.0.2 that we're planning to upgrade to 2.2.1 eventually (I don't want to upgrade to 2.3.0 just yet).

I'm aware of the documentation at https://kafka.apache.org/22/documentation.html#upgrade and I plan to follow each steps.

I'm just wondering if folks around here recommend to upgrade directly from 0.11.0.2 to 2.2.1 or instead do something like 0.11.0.2 -> 1.1.1 -> 2.2.1.
Also if anyone made the jump from 0.11.0.2 to 2.2.1 in production I'd love to hear your feedback, especially if things didn't work properly.

Thanks !
