But if I wish to downgrade later for some reason, I need the old PIX 6.3(1) image again. Right? But cisco.com's site has only 6.3(5). Can I use the downgrade command to downgrade to 6.3(5) when the actual previously installed version is 6.3(1)?
Or do i need to upgrade first to 6.3(5), then to 7.0, then be able to use the downgrade command to downgrade to 6.3(5)?
Caution Do not load a previous version of software if your PIX security appliance is currently running PIX Version 7.0 or later. Loading a software image from monitor mode, on a PIX security appliance that has a PIX Version 7.0 file system, results in unpredictable behavior and is not supported. We strongly recommend that you use the downgrade command from a running PIX Version 7.0 image that facilitates the downgrade process.
