If you are running OpenSolaris (IPS releases), you will need to upgrade it to OpenIndiana. Upgrading to OpenIndiana requires that you have OpenSolaris build 134 installed. You can check which build of OpenSolaris you are running by typing "
uname -v". If it reports a number lower than 134 (such as 111b), please update to 134 by following the guide in the next section.
For possibly more up-to-date or detailed descriptions, see the OpenIndiana Wiki pages regarding Installation and Upgrade of the OS:
