Nexus 93180YC OS upgrade with ISSU

[cokho]

We have a Nexus 93180YC for our Vcenter cluster. I have no luck finding a guide to upgrade NX-OS using ISSU.

Is ISSU a background service which require no user intervention?

what is the current nexus os, and what version are you looking for the target version?

is this vPC ? any orphan ports? most of the end devices are dual-homed.

BB,

- current OS is 9.3(5)

- target OS is 9.5(10)

- vPC configured

- end devices are dual-homed

thanks

Do you have any FEX connected ? are they dual homed ?

- target OS is 9.5(10)  - I take this as 9.3(10) ( there is no 9.5 nexus OS released)

check below matrix and guides (most is release notes and caveats)
