Why? Because we have vmware's server connected to both with protocol LACP. we won't wish to stop access the server.<BR /> <BR /> Is it possible? Transfer and reset only one?<BR /> <BR /> Fri, 13 May 2016 21:16:00 GMT https://community.extremenetworks.com/t5/extremeswitching-eos/upgrade-firmware-2-c5-stackable/m-p/56069#M716 Paulo_Silva 2016-05-13T21:16:00Z https://community.extremenetworks.com/t5/extremeswitching-eos/upgrade-firmware-2-c5-stackable/m-p/56070#M717 To be in a stack the switches must be on the same version of firmware so there is no way to upgrade them separately.
