Documenting your current configuration will give you a clear point of departure for the transition. Make a list of the following items:
Name and location of all current NIS domains and networks
Host name and location of all current NIS servers, both master and slave
Configuration of all current NIS servers, including:
Host name
CPU type
Memory size
Disk space available
Name of administrators with root access
Nonstandard NIS maps
Correlate the list of your NIS clients with their eventual NIS+ domains. They must be upgraded to the current Solaris operating environment.
