Can I upgrade from IOS version 12.2(53)SE2 to 15.0(2)SE9?

krishna3010 · ‎12-27-2016

Hi,

Can I upgrade directly from IOS version 12.2(53)SE2 to 15.0(2)SE9 on a 3750X switch ?

Or do I need to use any middle version before upgrading to 15.0(2)SE9 ?

Can someone help on this query please

Regards

Krishna K

Yes you can. Don't forget to read the Release Notes.

NOTE: The upgrade will automatically include a one-off "microcode upgrade" which takes about 45 minutes.

Thanks Leo for information.

My upgrade is scheduled for next week

BTW, Leo, in the past, has recommended later revisions of 55(SE) as very stable. Unless you need 15.x features, you might want to reconsider what version you want to upgrade to.

Correct, Joseph. I still do.

12.2(55)SE is the most stable IOS suitable for 3560- and 3750 series family of switches.
