Upgrading firmware for Nexus 3048

[mramirez-t]

We have 5 Nexus 3048 switches in production.  

4 of them running 6.0(2)U6(8)

1 of them running 6.0(2)U3(7)

We got alert that we should update the firmware due to some security vulnerabilities in the existing firmware.  I see that these are available now:

7.0(3)I4(8b)

9.2(2)

My question is, can I update immediately to 9.2(2) from where the firmware is now, or do I have to do the intermediary step of the 7.0(3) version first and then update to 9.2(2).

Any help is appreciated.  Thanks.

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/release/70348/n3k_70348_nxos_rn.html#_Toc499148913

Upgrade Matrix

This section provides information on upgrading Cisco Nexus 3000 and 3100 Series switches to Cisco NX-OS Release 7.0(3)I4(8).

Note: Beginning with the 7.0(3)I2(1) release, kickstart and system images are no longer used to install the Cisco NX-OS software image on Cisco Nexus 3000 and 3100 Series switches. Instead, a single binary image is used (for example, nxos.7.0.3.I4.1.bin). To install the software, you would use the install all nxos bootflash:nxos.7.0.3.I4.1.bin command.

From	To	Limitations	Recommended Procedure
7.0(3)I2(1)  or later	7.0(3)I4(8)	None	install all is the recommended upgrade method supported.
6.0(2)U6(3a)[1]	7.0(3)I4(8)	None	install all is the only upgrade method supported because of a BIOS upgrade requirement. Warning: Make sure that you store the pre-Release, 6.0(2)U6(3)’s configuration file. For more information, see the Cisco Nexus 3000 Series NX-OS Software Upgrade and Downgrade Guide, Release 7.x.
6.0(2)U6(2a)[2] or earlier	7.0(3)I4(8)	First, upgrade to Cisco NX-OS Release 6.0(2)U6(3a) or a later release. Note: A Cisco Nexus 3048 switch requires an additional step when you upgrade from a software version older than Cisco NX-OS 6.0(2)U6(2), otherwise the switch can fail to boot. You must first upgrade the switch to Cisco NX-OS Release 6.0(2)U6(2a), then to Cisco NX-OS Release 6.0(2)U6(3a), and finally to Cisco NX-OS Release 7.0(3)I4(8).	install all is the only upgrade method supported because of a BIOS upgrade requirement. For more information, see the Cisco Nexus 3000 Series NX-OS Software Upgrade and Downgrade Guide, Release 7.x.
