I believe that the character is the same; however, if they simply used
the conversion utility to convert their database, they could be having
some problems.  The one area where the 4D programming language changed
most dramatically was in links (they aren't even called that anymore;
they're called relations), and it's possible that their code needs to
be changed, or their relations set-up "properly" under 2.1.

Personally, I've recommended to anyone who has a 1.0x 4D db that they
have someone go through their code, and bring it in line with the
current set of standards for 4D programming; their are a number of
commands that, while they still are still supported under 2.x, so far
at least, are only supported for converted databases, and probably
won't be supported whenever 3.x comes out, if even when the next 2.x
comes out.  Simply using Acius' conversion tool and running with it is
not, generally speaking, a good idea.
