hi there,
i'm assuming you're using /etc/passwd
you can try the following steps:
on old server
=========
1. unshadow passwd and group
pwunconv
grpunconv
2. copy your old passwd and group files to your new server,
rename them to passwd.old and group.old to prevent confusion.
on new server
==========
3. unshadow your passwords and groups
pwunconv
grpunconv
4. edit passwd file (make backups before editing!)
vipw
5. in vipw go to the bottom of the file,
use the "r" command to read-in (import) the contents of passwd.old,
then delete duplicate entries like root, bin, daemon, etc.
save the file.
6. repeat steps 4 and 5 to edit group file
using vigr to import group.old
7. switch to shadowed passwd and group
pwconv
grpconv
8. verify integrity
pwck
grpck
good luck!
