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

In-place upgrades only: During the installation process, the DBMS Server setup asks whether all databases are to be upgraded; answer No. The install procedure automatically upgrades the iidbdb. If the upgrade of iidbdb fails, see the appendix “Troubleshooting Upgradedb.”

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.
