How You Upgrade to Older Versions That Require a Patch
Newer versions of Ingres distribute service packs. You can install service packs without having to install a base release of Ingres first.
UNIX: If you are upgrading to an older Ingres version that requires an overlay patch instead of a service pack, follow this procedure:
1. Run ingbuild. When asked whether you want to set up all the Ingres components, respond No. Exit ingbuild.
2. Install the Ingres patch.
3. Run ingbuild again. Select Current, then SetupAll.
4. Follow the prompts to complete the Ingres setup.
Setup now uses the fixed version.
