Reverting updates to previous versions

You can remove an update to a package in order to revert to a previous version by using the Roll Back 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 were saved locally for rollback or cleared the Save files for rollback check box on the Preferences page while upgrading, you must have the media or repositories that were used to install that version of the package. If you do not have that media, you cannot roll back to the previous version.

About this task

If you have updated a product package and want to remove the update and revert to the earlier version of the product, use the rollback feature. 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 information center at https://www.ibm.com/docs/en/installation-manager/1.8.5.

Procedure

  1. On the Start page, click Roll Back.
