You can remove an update 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 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 cannot 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 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 roll
back only one version level at a time.
For
more information, see the Installation Manager online help or Information
Center.
