Upgrade 2960S-48LPS-L to latest version

[coppolino97]

Hi all,
I have a Cisco Catalyst 2960S-48LPS-L
This Cisco switch is running 12.2(55)SE5 firmware at the moment, but I would upgrade it to the latest software release (IOS 15.2.2E9).
This switch is used in production, so I cannot reset it and perform upgrades.
Can I direct upgrade from 12.2(55)SE5 to 15.2.2E9?

How can I check Cisco IOS firmware upgrade path?

Thanks a lot

You can directly upgrade from 12.2 to 15.X

Download the image from Cisco :

read the release notes  and upgrade steps :

not sure we understand this, you looking with out relaod upgrade ? that is not possible, you need to have downtime - since after upgrade you need to reload the switch (stack of switches) to take effective of new IOS.

Hello @balaji.bandi ,

thanks a lot for your quick response!

>> You can directly upgrade from 12.2 to 15.X
Good to know! It is going to take a lot of time I read.

>> I read "release notes  and upgrade steps"
Noted, but I did not found information about minimum version.
I just found this table: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/15-2_2_e/release/notes/OL_32525_01.html#pgfId-1042020

Thanks for your help!

There is no minimum version, you can upgrade to any 15.X version from your existing version.
