Best practice Stage Upgrade (small timeslot)

[MarcP]

Hi all,

never used the staged upgrade so far, only scheduled upgrade in general.

Wondering whats the best way to to it.

Got 2 Corestacks and around 40 access switches.

My plan was to start with access switche (10am) then Core2-stack (10.30am) and Core1-stack (11am)

Is this realistic, using the staged upgrade?

Only got 1,5-2h timeslot to upgrade all.

Or is it better to Upgrade all together, as the swtiches wait until all switches downloaded its firmware / after 20minutes ?

Regards

Marc

as there is enough time, maybe the all together option is the best?

I can schedule it and the firmware should be download before and then upgrade on time.

Yes, it can work, but upgrading all switches together is often simpler and safer when the maintenance window is small, especially because Meraki pre‑downloads firmware and switches wait around 20 minutes before rebooting.

Meraki's staged upgrades are great when you have too many switches to upgrade in a single window, or
you have different allowable outage windows per group.
