In general, yes, it's common practice to do the 'rolling upgrades'. If I had to do my whole cluster at once, with an outage, I'd probably never upgrade. :)

Hi all, If I wanted to upgrade my NSD nodes one at a time from 3.5.0.22 to 3.5.0.27 (or whatever the latest in that branch is) am I ok to stagger it over a few days, perhaps up to 2 weeks or will I run into problems if they’re on different versions? Cheers Richard
