DS300 Firmware Upgrade 7.2.1 > 8.2.1

I have recently inherited some EMC rebranded DS300's.  They are running at 7.2.1 and have thrown some vuln's on a PCI audit.  I need to upgrade them to the latest firmware.  I have to go through EMC to get the firmware but I am wondering can I go straight from my current version to the newest version and if there are any caveats I should be aware of?


Current 7.2.1

Newest 8.2.1 ???

Migrating from FOS v7.2 to FOS v7.4

Any 8G or 16G platform operating at FOS v7.2.x must be upgraded to FOS v7.3.x before non-disruptively upgrading to FOS v7.4.0.

Disruptive upgrade to FOS v7.4.0 from FOS v7.2 is supported.
Firmware clean install to FOS v7.4.0 from FOS v6.4 or later without retaining any configuration is supported.



For addiitional information it is recommended that you download the full FOS v7.4.0 release notes from the Customer Support Portal (CSP).


For an overview of the Customer Support Portal as well as registering, etc. we have a CSP overview video posted on the communities at the link below:
