Installing a new version of InfoSphere Information Server in the target environment
You must install a new version of InfoSphere® Information Server before migrating InfoSphere Information Server from your source environment.
Before you replace an existing version of InfoSphere Information Server with
a new version, you need to export all assets from the source system. After
the export is complete, you can uninstall the existing version and
then install the new version. If you want your new installation to
use the same ports and location as the source installation or if you
are using the same Windows system,
you will have to uninstall before installing the new version.
