Cisco Nexus 5548UP upgrade from 5.0.3 to 7.0.1

Question

We have one cisco Nexus 5548UP L2 switch running very old software 5.0.3 version but recently i got 7.0.1 software from someone else (we don't have SmartNet on this switch).

is it safe to upgrade from 5.0.3 to 7.0.1? I was trying to find prerequisite but i didn't find any so wonder if some already did in past please share your experience.

UPDATE

after upgrade from 5.0.3 to 5.2.1 (for safety) look like my fan speed bump up from 50% to 60%. here is the show env output

Answer 1

Before proceeding with any upgrade, please ensure you have both the kickstart and the system image file. The kickstart file will set all the variables for you, and the system will check for this on reload.

NOTE: The kickstart file needs to match the system image file version. Please do not try to proceed with upgrading without both of these files.

The quickest way to determine if you are able to upgrade this device is by issuing the show install command from the 5548:

show install all impact kickstart bootflash:

Example Output:

switch-1# show install all impact kickstart bootflash:n5000-uk9-kickstart.4.2.1.N1.1.bin
system bootflash:n5000-uk9.4.2.1.N1.1.bin

Please also refer to the official documentation for upgrading from that version: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/upgrade/503_N1_1/n5k_upgrade_downgrade_503.html?referring_site=RE&pos=1&page=http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/upgrade/513_N1_1/n5k_upgrade_downgrade_513.html

Looking at the Release Notes usually tells you about supported upgrade paths. In your case, you don't have a choice. Basically - try it. Follow the directions in the Cisco Nexus 5000 Series NX-OS Software Upgrade and Downgrade Guide, Release 5.0

Also might look at the following.
