I like the video - but it doesn't explain the advantage of the enhanced vs the standard ISSU upgrades nor whether there are other possible downsides/upsides to boot mode lxc. (The latter is probably out of scope, but surely the former is not.)

vPC Upgrade Procedure for Nexus 9000 -R series switches: www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/92x/upgrade/guide/b-cisco-nexus-9000-nx-os-software-upgrade-downgrade-guide-92x/b-cisco-nexus-9000-nx-os-software-upgrade-downgrade-guide-92x_chapter_0110.html
@@CiscoSystems I think I should be ok here then. I actually only have customers on Nexus 93180YC - EX or FX. Sounds like I can do the "non-disruptive" on the secondary to 9.3(8) and then the Primary to 9.3(8). After that jump, I can load the EPLD code, which IS disruptive, but in vPC mode that should be fine.

Great explanation, simple and clear
Great short informative explanation

Do we have to copy the code on the second supervisor if we do a non-issu upgrade?

Is the standalone nxos.9.3.8 software the same software you use to upgrade a vPC pair of switches?

Cisco Nexus 9000 - Version 9.3(10) having high severity bug... go with 9.3(11) fixed version
CSCwc43397 - Memory leak in nginx process
CSCwc97953 - N9K Switch reloads due to SNMP process crashes after SNMP server reloads
CSCwc40911 - Memleaks in VPC (MCECM_MEM_fu_mts_wrap_t+ from mcecm_get_mts_wrap) after removing/recovering VPC
Upgrade will cause a traffic disruption. Since your line card hardware will not support non-disruptive upgrade
