PIX 506e OS Upgrade (How do I do it?)


I have never upgraded an OS on a PIX firewall but now I have to take OS 6.2.2 and put it to OS 6.3.5.

I have downloaded the pix635.bin file to my desktop and installed PumpKIN (TFTP server program).

Can someone please provide me with instructions on how to do this? Like I said im new at this, I have entry knowledge of PIX so try to make it make sense, cause i found a few sites online that explained it but they were written messy without explantion of what each command did and what needs to go there.

Thanks in advance

If you use the PDM remember to download the latest version of the PDM too. The following will show you how to upgrade the PIX.

since the file is on your desktop, the pix might have some trouble downloading it due to ntfs permissions - even if you move it to a new tftp directory, you will have to change the permissions most likely.
