Using the rollback feature, you can remove an update to
a package and revert to a previous version.
Before you begin
During the rollback process,
IBM® Installation Manager must
access files from the earlier version of the package. By default,
these files are stored on your computer when you install a package.
If you change the default setting or delete the files using the Remove
Saved Files option,
Installation
Manager requires
access to your installation repository or media. For the Remove Saved
Files option, click . If you installed
the product from a repository, you must have the repository used to
install the previous version of the product listed in your preferences.
To check the repositories that are listed, click . If you installed the product
from CDs or other media, the media must be available when you use
the rollback feature.
About this task
Use the roll back feature to remove an update that you
have applied to a product package. When you roll back a package, 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.
When
you roll back to an earlier version of a package, the package is restored
with the same features that are associated with that version. Use
the Modify wizard to add and remove features.

- In Installation

to roll back. Click Next.

back to. Click Next.

Back to roll back the package.
