I need a new software version 7.6.(3)

But

Can I use the high-availability image versioning feature to perform a software upgrade with the minimal downtime associated with the high-availability feature?.

How Can I upgrade the software image with the minimal downtime???

What is the procedure (step by step)?

Thanks

Thanks

HA versioning is not compatible with this version (and in reality, only very few versions are supported by versioning), so you will have to schedule a change window to upgrade the supervisor to 7.6.3. Once you upgrade the active, this will be synced with the standby supervisor.

Hi,

high-availability "hitless upgrade" is only a Cisco marketing trick which almost never works.

Yes, you can upgrade from 7.6.2 to 7.6.3 with no impact to your network. But who is doing such an upgrade in practice? Any time you try a real upgrade (7.1 to 7.6, e.g.) the image versioning says "not supported" which means three minutes outage of the switch.

Regards,
