Firmware 2920 3 switch stack

Hi,

 

I have 3 x 2920-48G switches in a stack configuration that i need to bring up to the latest firmware.

Thats easy enough to do but what i cant find an answer for is the following.

 

The stack is connected to two SANs and six clustered HyperV Hosts that have a lot of VMs running, is it possible to firmware the stack but only bounce one switch at a time so all the iSCSI connections etc can be kept connected accross the stack so all the VMs can be kept running?

 

Thanks.
