Upgrading Galera cluster

[Wayne Gemmell]

Hi Team

Is it possible to do a rolling upgrade on a galera cluster from mariabd 10.11 to 11.4? The documentation doesn't seem to cover this. 

Regards

Wayne

Hi,

This scenario is covered and there should be no issues. Just check the change notes and deprecated options.

Hi Stephan

Thanks for the feedback, it's good to know.

That document doesn't cover galera and the link below makes no mention of the 11.x series.

Hi Wayne,

It is possible to perform a rolling upgrade. Do you have a test set-up, I could walk you through it step-by-step and then you can replicate the same in your setup.

Regards!

Thanks for the offer Bihira. I'll be fine though. I'm not really worried about doing it. It's just that the other steps have specific documentation, I was worried that this wasn't supported. Good to know I can carry on testing.
