Rolling back updated packages by using wizard mode
Use the rollback feature to remove an update to a package and revert to a previous
version.
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 install a package.
- If you change the default setting or delete the files by using the Remove Saved Files option, Installation Manager requires access to your installation repository or media. To access the Remove Saved Files option, click . On the OS X operating system, the Preferences option is under the IBM® Installation Manager menu.
- If you installed the product from a repository, you must list the repository that you used to install the previous version of the product in your preferences. To check the repositories that are listed, click .
- If you installed the product from disks or other media, the media must be available when you use the rollback feature.
About this task
Use the rollback feature to remove an update that you 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.
- For installed fixes, a fix is uninstalled if the fix does not apply to the version of the product that you rolled back to. A fix is not uninstalled if you roll back to a version of the product that the fix applies to.
- The rollback does not reinstall the fix that was uninstalled during the fix pack installation.
Consider these examples:
- You installed Fix Pack 1 and Fix Pack 2. You also installed Interim Fix 2, which is applicable to both Fix Pack 1 and Fix Pack 2. If you roll back Fix Pack 2, you have Fix Pack 1 and Interim Fix 2 installed.
- You installed Fix Pack 1 and Interim Fix 1, which applies only to Fix Pack 1. You also installed Fix Pack 2. If you roll back Fix Pack 2, you have Fix Pack 1 with no fixes installed.
Note: You cannot roll back Installation
Manager to an
earlier version.
