Decide which version of the Solaris operating environment and NIS+ you will use for the transition. Because there are slight differences between versions, using multiple versions could needlessly complicate the transition process. Choose one version of the Solaris product and use its corresponding version of NIS+.
The current release has the most features (such as setup scripts). Make sure you compile a list of the Solaris 2.6 patches that are required for normal operation, and make sure that all servers and clients have the same patches loaded.
