The case for not ripping and replacing: Securing Win32 infrastructure in place
The default advice for any system running an unsupported operating system is simple: replace it. Upgrade to a supported platform. Move to modern hardware. Problem solved.
It’s good advice in theory. As with many other things in life however, in practice it ignores everything that makes legacy infrastructure hard to deal with in the first place.
For organizations running Windows XP, Server 2003, or other legacy 32-bit Windows systems, "just upgrade" is often the most expensive, disruptive, and operationally risky option on the table.
