I agree with John that it is a good time to consider a rewrite. You can
move from VAX (assumed from your description) to Alpha, take advantage
of the RTR (reliable Transaction router included in base O/S) and you
have the Retain Trust to protect the investment. Depending, web
enablement may or may not be the right way to go.
The reliability or otherwise of the infrastructure is then not your
concern because you control it in the VMS environment.
While this may appear to cost real money, compare it with what I expect
is a frozen VAX environment with zero cost over multiple years except
for electricity, a little housekeeping and hardware maintenance, the
cost of which may be increasing comparatively.
By your description, they already have the skills in-house (may need a
little additional help) to support an investment which will last for at
least the same number of years and will deliver the same or better
