Can I download a old version IOS12.2(25)SEB4 to the Catalyst 3750 which is currently running a new version IOS12.2(25)SEE2?

Thanks,

Yes you can download the old version from the following link.

Would require a CCO login with a valid contract though.

BTW, is there any specific reason why do you want to downgrade the IOS. New IOS versions have many bug fixes incorporated into them

HTH, rate if it does

Thanks for you kindly response!

We have a Catalyst 3750 with old IOS version which is online. Now, we bought another Catalyst 3750 with newer IOS version and want to stack it to the old one.

In order to avoid stacking version-mismatch, We need to make 2 switches in same version and keep the old switch working.

That's the reason we would like to downgrade the IOS. Do you have any advice?
