redwings,
To move over all users/groups I would follow the procedure below.
I am making the assumption that all home directories sit under /home.
Copy over and append
/etc/passwd
/etc/group
/etc/security/group
/etc/security/passwd
/etc/security/limits
/etc/security/lastlog
/etc/security/user
I tend to vi in the details for all non-OS users and edit out the duplicate OS entries. Once completed check the completeness and consistency of the files via:
usrck -y ALL
pwdck -y ALL
grpck -y ALL
tar up /home, copy over and restore.
Best of luck
