Roll back updates
Overview
Using the rollback feature, you can remove an update to a package and revert to a previous version.
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...
File | Preferences | Files for Rollback
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...
File | Preferences | Repositories
If you installed the product from CDs or other media, the media must be available when you use the rollback feature.
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 roll back only 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.
