Can I jump from 03.08.05a.E. to 03.11.02.E.152-7.E2.bin on the 4506-E.

[GilPalacio61960]

I need to Upgrade a few cisco 4506-E and the current Bootflash is: cat4500es8-universalk9.SPA.03.08.05a.E.152-4.E5a.bin.   I need to upgrade all these devices to:  cat4500es8-universalk9.SPA.03.11.02.E.152-7.E2.bin.    Will I be able to upgrade or so I need to go to a lower flash like:  cat4500es8-universalk9.SPA.03.08.06.E.152-4.E6.bin in order to scale it???  

I appreciate any assistance.

You can upgrade directly from 03.08.05a.E to 03.11.02.E.152-7.E2. Just make sure the current Rommon version is compatible with the new IOS.

Reza,  thank you for taking your time to answer this.   The Rom I have is the following:  ROM: 15.1(1r)SG6.   I Believe it will be compatible.   can you confirm? 

thank you,

GIL

Hi Gil

15.1(1r)SG6 is old and most likely is not going to work with the new IOS. So, upgrade to 15.1(1r)SG18 and you should be fine.

I am not sure if there is anything newer than 15.1(1r)SG18.

Reza, thank you.   I will do that!

When you upgrade, make sure to have someone onsite with console access in case something goes wrong.

Good Luck!
