is intermediate upgrade required if upgrading from present version 12.3.3.6 to 15.3.5.2-patch1-13 for switch model summit X450a

[Syed_Hammad_Jaf]

Extreme switch model summit X450a software needs to be upgraded to 15.3.5.2-patch1-13 . Present version is summitX-12.3.3.6.xos. Can we directly upgrade from 12.3.3.6 to 15.3.5.2-patch1-13? or do we need to an intermediate upgrade

Hi Syed,

I would suggest upgrading to the latest release of 12.6 first, then going to 15.3. While this isn't strictly necessary, 12.3 to 15.3 is a large jump to make directly.
