Is any upgrade steps available for upgrading Exos From 12.4 to 15.7

[Ragunath_S]

Can we directly upgrade from 12.4 to 15.7 without any issues
Some GA releases will erase configuration in switch.

yes

[Ragunath_S]

ok .. So no issue in upgrading the firmware from 12.4 to 15.7 directly if hardware supports

Hi Ragu,

Please check I/O & MSM Card EOL also before upgrade .
G48TA Line card & MSM G8X can not support version above 15.1.

if Line card & MSM is latest one than you can upgrade hitless from 12.4 to 15.7.

any model , there is any steps involved like 12.4 to 12.6 to 15.1 to 15.7

Ragunath,

There should be no issue with upgrading from 12.4 directly to 15.7.

What model switch are we looking to upgrade from 12.4 to 15.7?
