Fix Pack 8550

Uninstalling Liberty fix packs from distributed operating systems using the GUI

You can roll back WebSphere® Application Server Liberty Network Deployment to an earlier version using the Installation Manager GUI.

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 saved files, Installation Manager requires access to the repository that was used to install the earlier version.

Important: Installation Manager can install any fix-pack level of the product directly without installing the intermediate fix packs; in fact, Installation Manager installs the latest level by default. For example, you can skip fix-pack levels and go from Version 8.5.5.1 directly to Version 8.5.5.5. Keep in mind, however, that later you can not roll back to any level that was skipped. If you directly install to Version 8.5.5.5, for example, you cannot roll back to Version 8.5.5.4. If you skip from Version 8.5.5.1 to Version 8.5.5.5, you can only roll back to Version 8.5.5.1.
Note: In WebSphere Application Server Version 8.5.5.0, the Liberty profile was promoted from a feature to an independently installable offering. After updating to WebSphere Application Server Liberty Network Deployment Version 8.5.5.x from Version 8.5.0.x, you can roll back to the Version 8.5.0.x Liberty profile feature level that you were at before updating. If you previously had a combined full-profile and Liberty-profile installation, the Liberty profile feature will be reinstalled to the wlp folder when you roll back. Any user data and server configurations will not be restored. If necessary, you can copy them from the backed-up location into the new wlp/usr folder after rollback. If any wlp.bak_<timestamp> directories are present in your installation image, they will not be affected by the rollback. If you update and roll back multiple times between Version 8.5.0.x and Version 8.5.5.x levels, therefore, you will have multiple wlp.bak_<timestamp> folders in your installation image. These can always be deleted, copied, or moved without negative impact to your installation.
