I've received many posts from people on pitfalls to avoid in a 3.2c
to 4.0 upgrade. There are several repeated strains, sometimes conflicting:

View 1: Can't do it directly
--------------------
       I did. The biggie is that you can't go from 3.2c to 4.0 , you
need to be at (I believe) 3.2d or above to upgrade. Upgrade to a higher
version of 3.2 and then it's cake to do the upgrade (we had no problems) .

View 2:  You can do it but make sure there's enough file space
         in root partition.
        Lots of people have upgraded.  I think the biggest thing to
        watch for is the space that the new root file system wants
        to use.  This is probably mentioned in the release notes.

View 3:  4.0 is buggy...go to 4.0b as long as you're upgrading
Hi,
I did DU 3.2d-1 to DU 4.0 last summer. Not exactly the same but close.
The upgrade was similar to other unix upgrades, I have done in the past.
It is a major upgrade and tedious.
I also did DU 4.0 to DU 4.0A last October. I plan to do DU 4.0A to
DU 4.0B this week.
DU 4.0 has alot of bugs/issue, many were fixed with DU 4.0A. There have
been more issues corrected in DU 4.0B.
If you are going to do the upgrade I suggest you do not stop at DU 4.0.
 
        DU 3.2C to DU4.0 to DU4.0B
Unfortunately, you cannot go directly from 3.2C to 4.0B <SIGH>
I guess the main reason I am writing is that 4.0 is buggy.
                                                                                                                                                   
Other problems:
1 - older versions of NCSA Telnet client for DOS didn't work;
    users were immediately logged out. After upgrading their
    software, they're in good shape.
2 - csh users who had extraneous exclamation points (interpretable
    as bad history syntax) or references to non-existent user
    home directories in aliases) in their .cshrc or .login
    files were immediately logged out
-----------------------------------------------
So the bottom line is.. some people have told me 3.2c to 4.0 can't be 
done, others have told me it can.  There's one or two who said that
they've done it.  Unless someone else tells me for sure it can't be
done, I'm going to try it on one of my machines.  Thanks everyone
for your help
