The Question is:
one of our customers has an old uVax 3400 running VMS 5.2. Is it possible to
run UCX 4.x on this system or is an upgrade required to VMS 5.5-2?
The Answer is :
The OpenVMS Wizard would encourage an upgrade to OpenVMS VAX V7.2,
the current release, and TCP/IP Services V5.0A, the current release.
The OpenVMS Wizard would not particularly expect TCP/IP Services V4.2
to operate on something as old as OpenVMS VAX (or as it was then
known, VAX/VMS) V5.2. The oldest officially supported OpenVMS VAX
release for TCP/IP Services V4.2 is OpenVMS VAX V6.0, though some
folks have gotten V4.2 to (mostly) work on V5.5-2.
