I am currently involved with a couple of related projects in the corporate ecosystem which is populated my MBA dweebs. These people want absolutely "zero surprises" so I am afraid I would have to agree with the project lead that the only way forward is to go with an Emulation solution like Charon-VAX running on some sort of x86-64 platform like a DL385.

In the case of VMS or OpenVMS, many hope that the system can be ported later (harder after you loose talent) or the company can eventually migrate to some sort of cheaper wiz-bang Linux solution. I can tell you that going the Linux way can open up a whole new problem as I have documented here:

IBM will not give ROOT or SUDO privs to anyone without first submitting a written request then you need to wait 4-8 weeks for the response depending upon the urgency.

Are you satisfied with the backup of your system's disks?
It doesn't just apply to VMS. And actually, it's not the backup
that matters, it's the ability to restore it (or recreate an
equivalent) and carry on from something resembling where you
left off. It's helpful to know in advance whether you stand
much chance of it working right. In your picture, with Linux
systems managed by external commercial contractors (same
company that does the admin is also the one that owns the OS
provider, right?), who is technically and financially
responsible for making sure that systems can be restored or
rebuilt?
(2) This would all be fine if you were using (someother)
Linux/BSD etc. My favourite Linux of the Week has been
Suse, for a decade or more.
(3) Have you considered blaming any problems on systemd?
Lots of Linux/BSD/etc folk seem to be doing it, and I
don't like the sound of systemd much, but it hasn't
broken any of my Suses yet, so far as I know.
(4) The cult of "seagull management" vs "continuous
improvement": if things don't change, they're not
improving, so high-flying managers come in, cover the
place in .. (eg by changing stuff that works) and reap
their rewards and move on before the changes are seen
to be disasters in waiting. Been there, seen that,
not a bright idea in critical systems expected to
last longer than a few seasons.
Still, what could possibly go wrong.
