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.
