You can remove an update, such as a fix pack,
to a product package to revert to a previous version by using the
Roll Back Packages 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 have deleted the files that are saved locally for
rollback or cleared the
Save files for rollback check
box in the Preferences page (
File > Preferences > Files
for Rollback) while upgrading, you will not be able to
roll back to the previous version without the media or repositories
that were used to install that version of the package.
About this task
Use the rollback feature if you have applied an update
to a product package and decide later that you want to remove the
update and revert to the earlier version of the product. When you
use the rollback feature, Installation Manager uninstalls
the updated resources and reinstalls the resources from the previous
version. You can only roll back one version level at a time.
For
more information, see the Installation Manager online
help or Information Center.

Manager.
