Switch firmware update

[CarlMontminy]

Hello,

We have about 50 switches to upgrade. Our two main models are ICX 6450 and ICX 7250 and these are the firmware’s currently installed on them:

ICX6450:

SW Version 07.4.00bT311             Firmware ICX64S07400b               Boot-Monitor 07.4.01T310 (kxz07401)

SW Version 07.4.00T311               Firmware ICX64S07400                  Boot-Monitor 07.4.00T310 (kxz07400)

ICX7250:

SW Version 08.0.90dT211             Firmware SPS08090d     Boot-Monitor 10.1.15T215 (spz10115)

SW Version 08.0.30hT211             Firmware SPS08030h     Boot-Monitor 10.1.06T215 (spz10106)

SW Version 08.0.90jT211              Firmware SPS08090j       Boot-Monitor 10.1.18T215 (spz10118)

We will probably need to upgrade the boot monitor and the firmware since they are all pretty old.

Are we going to lose some licenses in the process? (Ex: 13-base-2X10G)

Should we move to an earlier version before going to the most recent one or going to the most recent firmware version will be fine and compatible?

Your help would be much appreciated.

Kind regards,
