ISSU in 9407R in stackwise virtual

[amine_sto]

Hi,

We have configured two catalyst 9407R with stackwise virtual and we have dual supervisor on each chassis.

while preparing to upgrade to fuji 16.9.5 using ISSU, i found this limitation :

"With Cisco StackWise Virtual configured on the switch, ISSU is supported only in single supervisor
module configuration"

Knowing that in stackwise virtual the backup supervisor on both chassis are basically powered off, is it possible to use ISSU for this upgrade or i'm gonna need to separate the two switches?

ISSU/FSU/eFSU is not supported so the unpacking of the firmware can be done on the active card (and gets pushed to all the other cards), HOWEVER, both chassis will need to be rebooted at the same time.

OK, so ISSU is supported on virtual stackwise only if we have one SUP card by chassis ?

and will the other SUP cards that are powered off also be upgraded ?

Thank you.
