Preupgrade assistant analyses the system to assess the feasibility of upgrading the system to a new major version. Such analysis includes check for removed packages, packages replaced by partially incompatible packages, changes in libraries, users and groups and various services. Report of this analysis can help admins with the system upgrade - by identification of potential troubles and by mitigating some of the incompatibilities. Data gathered by Preupgrade Assistant can be used for in-place upgrade or migration of the system. Migrated system is a new system installation retaining as much of the old system setup as possible.
