SUMMARY: How to upgrade a NIS+ server from Solaris8 to Solaris 9

Thank you to Daryl McKinnon, who had 2 suggestions. I plan to work on this
next week. The suggestions are as follows:

Option 1:

        Use the following steps to make a copy of the NIS+ files before the
upgrade
        (I would suggest single user mode):

        # tar cf /nis_save.tar /var/nis /etc/.rootkey /etc/nsswitch.conf
        /etc/defaultdomain

        Then after the upgrade, again in single user mode, untar the files.
You
        should be ok (I've done this a few times).

        Of course I'd make a backup of the entire system just in case
anything else
        went wrong.

Option 2:

        You could also make a standard NIS+ client, make it a replica server
and promote it to a master. You would have to downgradee the original master
to a normal client. Then upgrade the OS on the old master, and point to the
new server for NIS+ services. Once the upgrade is done, you can promote it
back to being a master server.
