Uninstall the old
software
If the new version of the product is functioning properly, all data has
been migrated to the new version, and all services are functioning properly,
you should uninstall the previous version of the product.
Uninstalling the previous version of the product will prevent conflicts
if the previous version is started by mistake while
is running.
Chapter 9, “Performing an
Uninstallation,” provides more information.
Uninstall will display errors if services were installed by the
installation program when the old version was installed, but were removed
manually in a later step. The uninstall process will display errors because it
will not find the services when it tries to remove them.
