The version-to-version migration wizard is a graphical interface that guides you through migrating from an older version to a newer version of WebSphere® ESB.
The migration wizard uses the WBIPreUpgrade command and WBIPostUpgrade command to migrate the data and applications from the older version to the newer version of WebSphere ESB.
This step transfers applications and configuration information for the older version's server resources, security, variables, and virtual hosts to the newer version's server. All stored information is in XML files in the profile_dir/config/cells directory of each product.
The WBIPreUpgrade tool saves selected files from the install_root and profile_root directory to a backup directory you specify on a wizard panel. Migration saves files to the following subdirectories in the backup directory: profiles/profile_name and websphere_backup.
Later, the migration wizard uses the WBIPostUpgrade tool to restore a selected profile environment in the backup directory into the newer WebSphere ESB profile environment
