The new OneFS 9.3 code is available on the Dell EMC Online Support site as both a  reimage file for configuring new clusters with 9.3, and an upgrade package for legacy clusters.

For upgrading existing clusters, the recommendation is to open a Service Request with Dell – EMC Support to schedule an upgrade. To provide a consistent and positive upgrade experience, Dell EMC is offering assisted upgrades to OneFS 9.3 at no cost to customers with a valid support contract. Please refer to Knowledge Base article KB544296 for additional information on how to initiate the upgrade process.
