| Description: | Preupgrade Assistant analyses the system to assess the feasibility of
upgrading the system to a new major version. Such analysis includes a check for
removed packages, packages replaced by partially incompatible packages, changes
in libraries, users and groups, and various other services. A report of this
analysis can help admins with the system upgrade by identification of potential
troubles and by mitigating some of the incompatibilities. The data gathered
by Preupgrade Assistant can be used for the in-place upgrade or migration of
the system, where the migration means a new system installation that retains as
much of the old system setup as possible. |
