Does anyone know from start to finish how much time the switches take to upgrade and become operational again?&nbsp; I am planning on upgrading each one separately but in the same downtime if I get approval.&nbsp;</P> <P>&nbsp;</P> <P>Thanks</P> <P>Lorna</P> Mon, 06 Jan 2020 23:56:14 GMT Lorna_Racano1 2020-01-06T23:56:14Z https://community.extremenetworks.com/t5/extremeswitching-eos/s8-firmware-upgrade-time/m-p/78914#M2159 <P>Hi</P> <P>I have two&nbsp;S8 Chassis that have very old firmware on them that need to be upgraded.&nbsp; Each Chassis has 6 blades in them.
