I have attemted to downgrade a PIX 515 from OS 7.2(2) to 6.3(5) by issuing 'copy tftp flash' on the PIX cli.
The file has been downloaded ok - and is sitting in flash:/
However the PIX is still using version 7.2 after a reload. Can anyone tell me how I can get the PIX to use 6.3(5). There are 3 files in flash:/ - image_old.bin image.bin and pix635.bin (the one I've downloaded).
Many thanks if anyone can help.
