Planning NIS+ Upgrade

NIS+ supports the following combinations of operating environments:

• SunOS release 5.7 software installed on all servers and clients

• SunOS release 5.7 software installed on one server, but combined with some SunOS release 4 servers

  For a network, there are three main migration paths from NIS to the NIS+ name service:

• Upgrade all servers and clients to NIS+

• Upgrade all servers at once to NIS+ and enable its compatibility mode to support SunOS release 4 clients

• Use different domain names so NIS and NIS+ can coexist

  The first step to upgrading your network is to decide which servers to upgrade to the NIS+ name service and which servers can continue to run NIS. See NIS+ Transition Guide for more information.
