I recently solicited suggestions on making the transition from VMS to
Ultrix.  Connecticut College currently has a MicroVAX II running Ultrix
and a VAX/8350 running VMS.  We are planning to switch to Ultrix on the
8350 and eliminate the MVII.

The following summarizes the responses I received.  Thanks to all who responded.

        We've considered this.  The expense of transferring software
        licenses (VMS, SPSSx, SAS, Minitab) would be our main reason not
        to do it.  Also, we've only been a VMS shop for 12-18 months, and
        being a liberal arts school, we haven't developed a "hard-core"
        VMS user base.

        If we'd have planned ahead a few years ago, that'd be an option
        to give serious consideration.  However, I understand that
        BSD4.3 will NOT run on a VAX/8350.  The 8350 has a dual-processor
        CPU which is not supported by BSD4.3.

        We considered EUNICE when we first purchased the 8350 and the
        MVII.  At the time we were concerned about efficiency and
        compatibility.  Now, I think I'd rather try to find a DCL-like
        shell for UNIX than keep VMS around that much longer.

        We plan to investigate Dcl8 and VCL further.  I've already
        contacted Boston Business Computing and the prices for VCL and
        their EDT-like editor are the same.  They each range from $495 on a
        VAXSTATION 2000 to $3995 on a VAX 6320.

        We are more likely to go along with the last suggestion.  The
        number and sophistication of our VMS users is such that guiding
        them to the appropriate Unix command will probably be
        sufficient.  I'd hope they'd get the hang of Unix in just a
        few sessions.  There are probably less than a dozen commands
        used on a regular basis.  We also plan to offer some Unix workshops
        over the summer and early next semester.

        Most of our VMS users use EVE (EDIT/TPU) as opposed to EDT.  We
        will probably look at some flavor of emacs and plan on defining
        some standard function key assignments to help the users.  Emacs
        and all those control/escape sequences can be a bit confusing.


Thanks again to everyone who responded.
