I've done rolling upgrades of point releases without issues (replica 3 
volume), so long as you're slow and methodical I don't think its an issue.

Major upgrades of any system tend to involve pain - I know the ceph 
upgrade from Hammer to Jewel (9.x - 10.x) was a non trivial procedure 
that involved taking the cluster down.
