You can install the latest version of OpenROAD into the same Ingres instance. Doing so will automatically uninstall the previous version of OpenROAD before installing the new version. If the OpenROAD 5.1 Standalone Net Client option was chosen, OpenROAD 11.2 will not upgrade the OpenROAD 5.1 Standalone Net instance. If the OpenROAD 11.2 Standalone Net instance is chosen, then a different Ingres installation identifier will be used. OpenROAD 11.2 can only be installed with an OpenROAD 11.2 Standalone Net client or an Actian X 11.1 instance (DBMS or Client). The Ingres 11.2 Client runtime cannot be used as a target for OpenROAD 11.2.

This method will not uninstall OpenROAD 3.5. In most cases OpenROAD 3.5 will be installed into an Ingres 6.4, OpenIngres 1.x, or Ingres 2.x instance. The OpenROAD installer will not allow OpenROAD 11.2 to be installed into these installations.

If you want to compare the previous version of OpenROAD with OpenROAD 11.2 side by side, you may install OpenROAD 11.2 in a separate Ingres instance.
