Copying user accounts to non-SCO UNIX systems

System Administration Guide
Chapter 1, Administering user accounts

You can migrate user accounts to other XENIX or UNIX systems by copying the /etc/passwd (and /etc/shadow, if applicable) to the target system. If the target system does not use /etc/shadow, run the pwunconv utility to consolidate the information into /etc/passwd before copying the file to the target system.

NOTE: If you need to migrate accounts to another SCO system, use the ap(ADM) utility described in ``Copying user accounts''.
