First and foremost I would like to send a hearty "Thank you" to the
following users for their insightful comments:

It appears that NIS and NIS+ can work together just fine. To get them to
coexist:
* Install NIS+
* Change /etc/defaultdomain back to NIS domain
* Modify /etc/nsswitch.conf to query NIS before NIS+
* Reboot
I am not sure if a reboot is necessary. I've installed NIS+ a couple times
now, and have backed out the installation each time using `nisclient -r`.
Both the NIS+ manual and one of the replies (from Arash Jahangir) mentioned
that a reboot was in order. However, NIS appeared to work just fine without
a reboot. (I'm not one for rebooting machines -- especially our servers)
In any case, both NIS and NIS+ are running on the machine -- using NIS as
the main querying mechanism. Now, whenever I need to do NIS+-type stuff, all
that needs to be modified is the domainname.
Again, thanks to all that have replied!

I just asked the exact same question from Sun Support and they said that it is possible. When you install NIS+, change the domain name to your testdomain first and make sure that the nsswitch.conf file is correct. Once you are done with your installation on the NIS+ server, then switch the nsswitch.conf and the domainname back to what they were, and reboot the machine. Make sure that ypbind is running. Anytime that you want to do some NIS+ related work on the server (say add replica's) you will have to switch the domainname back to the test domain. Hope this helps.

If you have a 690MP model 120 or model 140 with the old A.7 version CY605 CPUs then your machine will only run in "uni processor mode" under Solaris 2.4.
If your CPUs have a too old version you will see the following warning message during installation of Solaris 2.4 :
WARNING: DOWN-REV ROSS 605 CPU DETECTED - PLEASE UPGRADE. RUNNING IN UNI-PROCESSOR MODE. PERFORMANCE WILL BE AFFECTED.
We have 6 670MP machines, all with the old A.7 version CY605 CPUs.

Well, I have never tried it, but I don't think there are any reason why it shouldn't work. You can configure the "order" in which services will be used in the file /etc/nsswitch.conf. Thus, by making sure you use NIS before (or instead) of NIS+ in that file, NIS+ shouldn't be used by your "normal" system. Thus, you can play around with NIS+ as much as you like.
Let us know how it goes! :)

Yep
Just make sure you have nis before nisplus in nsswitch.conf for all important services, and you will have to run the same domainname
