[NBLUG/talk] Integrating usernames/passwords

If one was responsible for, lets say, 1,000 users and wanted to move the 
users to another machine, how can one just add those that are not 
already in the destination machine?

For example, we have the online machine, "A", and the new machine, "B".  
pwunconv and grunconv has been run on /etc/passwd and /etc/group, so the 
task is to add those usernames in the /etc/passwd file on "A" that are 
not in /etc/passwd on "B" (off course, the shasow files would be 
recreated after this is completed).

Will this approach work and is there a script available that checks to 
see if a username is in the destination and if not, will copy it into 
the destination?  It has been many years since I wrote some Perl 
scripts, but I would imagine that with Perl this would be a piece of cake.
