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
