You can remove an update to a package in order to revert
to a previous version by using the Roll Back wizard of IBM® Installation Manager.
Before you begin
During the rollback process, Installation Manager must access
files from the earlier version of the package. By default, these files
are stored on your computer when you upgrade to a new package. If
you deleted the files that were saved locally for rollback or cleared
the
Save files for rollback check box on the
Preferences page while upgrading, you must have the media or repositories
that were used to install that version of the package. If you do not
have that media, you cannot roll back to the previous version.
About this task
If you have updated a product package and want to remove
the update and revert to the earlier version of the product, use the
rollback feature. When you use the rollback feature, Installation
Manager uninstalls the updated resources and reinstalls the resources
from the previous version. You can roll back only one version level
at a time.
For more information, see the Installation Manager
information center at http://www.ibm.com/support/docview.wss?uid=swg27010911.
Procedure
