I worked in industry and most plant operators and owners are cheap SOB's. If anything important is very old and obsolete they will have spares ready to go if the machine is that important and 3rd parties contracted to do any work as needed (nobody running the machine would know how it works anyway).
Replacing some old working gear with something new can be VERY expensive and then there is the time and paperwork required to requalify it and whatever new proceedures are needed for ISO certs.
