To install Ingres, see the Ingres installation instructions for your platform.

During the installation process, the DBMS Server setup asks whether all databases are to be upgraded; answer No. The installation procedure automatically upgrades the iidbdb. If the upgrade of iidbdb fails, see the chapter “Troubleshooting Upgradedb.” It is better to complete the Ingres setup, and then use the upgradedb command to upgrade the user databases.

If you are upgrading from 6.4, and the 6.4 installation has Ingres Star databases, you must respond No to this prompt. At this point in the 6.4 upgrade, the Star Server is not yet set up.

After the iidbdb is upgraded, the DBMS Server setup attempts to upgrade imadb and install Remote Command Server objects into imadb. Some versions of upgradedb neglect to create imadb first, and you will get “Database does not exist: imadb” errors. These will be corrected in the next step.
