Thanks Kevin and Bob. PTF = minor version? I can’t think what it might stand for. Something Time Fix? Point in time fix?

Richard,

 

I will second what Bob said with one caveat … on one occasion we had an issue with our multi-cluster setup because the PTF’s were incompatible.  However, that was clearly documented in the release notes, which we obviously hadn’t read carefully enough.

 

While we generally do rolling upgrades over a two to three week period, we have run for months with clients at differing PTF levels.  HTHAL…

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
