To change an object's group, use the following syntax:
nischgrp group object
group is the fully qualified name of the object's new group.
object is the fully qualified name of the object.
Be sure to append the domain name to both the object name and new group name.
The example below changes the group of the hosts table in the doc.com. domain to admins.doc.com.:
client% nischgrp admins.doc.com. hosts.org_dir.doc.com.
