These conversion problems have been addressed.  The new news will
understand articles sent to it in the old format, and a program
to send articles to old format systems will exist.

Converting the users and database to the new format is messy.
We considered writing a program to convert everybody, but we
came up with a much simpler solution: have people run the old
news program to read stuff up to the date of the changeover,
then run the new news program to read new stuff.  The last article
posted on the old system before changeover should consist of
instructions to switch to the new versio (which will be called
'readnews' rather than 'news' or 'netnews').  Shell scripts to
first run the old version, then the new version, can be made easily
if desired.  Presumably after a short time (say, a week or two)
the old news can be uninstalled.  This will give most people plenty
of time to log in and read the old news - those who don't log in for
a week (or whatever time a site chooses) will get a message such as
'netnews: command not found' when they finally do log in, and will
presumably ask someone what happened.

Comments on the conversion process are welcome.
