Second that.  We upgraded 3 (2-node) clusters from 9.3 to 9.7 in June without any issues.  Our clusters have cascading snapmirror/snapvault relationships so the extra layover at 9.5 and only upgrading one cluster at a time resulted in a long maintenance window but otherwise it was all smooth.

Hey,

this works well and yes, your assumption is correct, two upgrades per node.
We‘ve upgraded at least 20 HA-pairs using that method with not a single issue.

Best,

Hello Toasters,

Anybody have experience, positive or negative,  upgrading from 9.3 to 9.7?

It is a supported automated upgrade path but requires packages for
both 9.5 and 9.7.   My understanding is each node will be upgraded
twice (once to 9.5 then to 9.7) but otherwise should follow the
typical automated upgrade routine.

Thank You
Phil
