iPlanet Web Server 4.1 provided two methods for creating hardware virtual servers: the object method and the virtual method. Migration of hardware virtual server information depends on which method you used:
If your iPlanet Web Server 4.1 hardware virtual servers were created using the object method, these hardware virtual server settings are migrated from the 4.1 obj.conf file to the 6.1 server.xml file.
If your iPlanet Web Server 4.1 hardware virtual servers were created using the virtual method, these hardware virtual server settings are migrated from the 4.1 virtual.conf file to the 6.1 server.xml file.
iPlanet Web Server 4.1 software virtual servers settings are migrated from the 4.1 obj.conf file to the 6.1 server.xml file.
