Nexus 5500 L3 Routing - upgrade ISSU?

[oguarisco]

Hello,

we need to perform a SW upgrade on a 5.X Release on a pair of Nexus5500 with Dual-attached FEX and L3 daughtercard installed with IP Routing enabled.

I've read that ISSU Upgrade is not possible with L3 Routing feature active, and we should do a disruptive upgrade of each switch requiring a reboot...is this confirmed?

Thanks for a reply

O.G.

Yes. ISSU isn't supported with the L3 daughter card installed and active. 

Confirmation:
