C9300L-48P-4XL IOS UPGRADE

[marzi]

Hi all

I've six C9300L-48P-4X-E with release Cupertino 17.07.01 onboard.

I've seen that there is a bug in the release 17.07.01 and in the release 17.08.01.

The question is : can I upgrade form 17.07.01 to 17.09.01 directly ?

or upgrade from 17.07.01 to 17.09.03.

(The release 17.09.02 has a bug.)

I see that the suggested releases are : Bengaluru 17.6.5 or Amsterdam, 17.3.6, I should do a downgrade, I suppose.

Please any suggestion are welcome for clarify my ideas

Thanks in advance

you can directly upgrade. but check recommended version is software download list. better to upgrade/downgrade to recommended version

@marzi latest recommendation is  https://software.cisco.com/download/home/286322093/type/282046477/release/Bengaluru-17.6.5

Hi

 Yes you can.  

 As you can see on the print below, Cisco gives example about upgrade from previous version 16 to 17.9

Direct upgrade is supported, however, I strongly recommend going straight to 17.9.3 because End-of-Sale announcement for 17.6.X has been made on October 2022.
