You can use the IBM® Installation
Manager rollback feature to revert an updated package back to a previous
version for those packages that support rollback.
About this task
To complete the rollback, the Installation Manager requires
information from the earlier version of the package for those packages
that support rollback. By default, the files that are needed to complete
the rollback are saved on your computer when each version of the package
is installed. On the
Files for Rollback preference
page, you can change the default action and remove any previously
stored files.
