| Description: | Preupgrade assistant performs assessment of the system from
the "upgradeability" point of view. 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 the admin with the inplace upgrade - by identification of potential
troubles and by mitigating some of the incompatibilities. Data gathered
by preupgrade assistant can be used for the "cloning" of the system - new,
clean installation of the system, as close as possible to the old RHEL setup.
In addition, it provides some postupgrade scripts which are supposed to finish
migration after the installation of RHEL-7 system. |
