The AppleShare IP Migration utility preserves existing user and group accounts (and, optionally, other data) without using export files.
Each chapter provides instructions for using these tools as appropriate.
System Accounts
When you install the server, several user and group accounts are created automatically. These predefined accounts are sometimes called system accounts, because they’re used by the server system software. See the user management guide for a description of how predefined accounts are used.
You can’t change the names or IDs of system accounts. So when you migrate users and groups, make sure you don’t try to do so. However, you can add users during migration to two system groups: admin and wheel:
•Wheel is a group that gives members almost as much control as root. If you’re a member of the wheel group, you can use the su (superuser) command in the Terminal application to log in to a remote computer as the root user. Use ssh to log in, type su, then supply the root password when prompted.
•The admin group gives members the rights to administer Mac OS X Server. Admin users can use server management applications and install software that requires administrator privileges.
Here are the predefined user accounts:
