I'm told that HP can't be trusted to continue with OpenVMS and they may discontinue the Itanium Machines. Also, it's too hard to find VMS Experts in the work force. Also, I'm told that the industry is moving from OpenVMS to Windows everywhere.

iFix was purchased by GE several years ago. GE has a product whose
name
has morphed over the years. In 1988 GE developed and marketed a
product
called Cimplicty. This ran on VMS and provided "graphical" screens
using Regis.
Over time Cimplicity ran on VMS, UNIX and finally Windows. It's
current version
is v8.2 and seems to allow painless migrations from older versions.

iFix is not Cimplicity, different roots.

V Systems still markets a product that operates on VMS. Very robust
and
stable.

Swapping out a SCADA (old term these days) is not for the faint of
heart, especially
on the system as described.

Good Luck

Note: I am not an expert, talk is cheap, comments are free. I have
been doing "SCADA"
systems for over 30 years and have picked up a few tid bits in that
time.
