Installing WebSphere Adapters

Migration of an installed adapter

If you previously installed an earlier release of a WebSphere® adapter on your workstation, the adapter installation backs up the older RAR file and other adapter artifacts before installing the new release. See the documentation for your WebSphere adapter for any other migration information.

If the installer detects a previous version of the adapter, the installer creates a backup directory and moves the installed adapter files into this directory before proceeding with installation. The adapter installer does this as follows:
  1. Checks for the existence of the adapter RAR file in the installation location.
  2. Reads the version of the adapter from the ra.xml file inside the adapter RAR file.
  3. Creates a backup directory named <adapter>_backup at the same level as the previous directory.
  4. Copies the files and directories under the <adapter> directory into the <adapter>_backup directory.
  5. Renames the copied directory to <adapter><version>_backup.
  6. Removes the original directory under the <adapter> directory.

The following figure illustrates the backup directories created by the installer.
