Nexus 9000 ISSU - done more than once

[micahbarsness]

We have two separate C9348GC-FXP's.

Can you do multiple non-disruptive upgrades in a row or is it required to reboot at least once every two upgrades?

example: We upgrade from 9.2(4) to 9.3(1) using ISSU non-disruptive. Then next time we upgrade (9.3(1) to 9.3(3)) will we need to perform a disruptive upgrade so that the device reboots?

it required reboot each update, every upgrade need reboot to take effect of new version.

I thought the point of the upgrade using ISSU was so that you didn't have to issue a reboot.

Not sure how you understand ISSU here.

Cisco IOS ISSU capability extends Cisco's high availability innovations for minimizing planned downtime.
