IOS upgrade

[cowetacoit]

I need to upgrade the IOS on my 4506, sup 4. It is currently running 12.2.18-EW3 (DF). I'd like to get a lot newer IOS on there. But i'm stuck on deciding which one to upgrade. 12.2.44-SG (ED)is the newest one i can find. What is the difference between the EW and SG?

delete bootflash:cat4500-ipbase-mz.122-40.SG.bin

I actually just tried it.

Admin_4506#delete ?

/force Force delete

/recursive Recursive delete

bootflash: File to be deleted

cat4000_flash: File to be deleted

nvram: File to be deleted

slot0: File to be deleted

Admin_4506#delete bootflash:?

bootflash:cat4000-i9s-mz.122-18.EW3.bin bootflash:cat4500-ipbase-mz.122-40.SG.bin bootflash:cat4500-ipbasek9-mz.122-44.SG.bin

bootflash:flash

ok, so as far as the upgrade....

boot system flash bootflash:cat4500-ipbasek9-mz.122-44.SG.bin

Thanks! I'll try it again tonight.

Were you able to delete it?

You can verify by typing dir once again.

How about the boot system command?

Did you modify it per my suggestion?

Noticed, you had the missing location where the file was stored and the ".bin" in the filename was also missing.

Let us know how it goes.

HTH,

Yes i deleted all but the oldest and the newest.

Yes, the boot system flash "filename" you suggested works.

I did delete the file name "flash" as well.

Thanks for your help. I'll try the upgrade when i can have downtime again.
