Migrate from 7,8,9 to 9.1

Avant toute chose, faites une dernière mise à jour du système dans sa version actuelle.

No updates needed to update system to 9.0-RELEASE-p5.

S’il y avait une mise à jour redémarrez.

Ensuite on passe à l’upgrade:

FreeBSD 9.1-RELEASE (GENERIC) #0 r243825: Tue Dec  4 09:23:10 UTC 2012

Welcome to FreeBSD!

Before seeking technical support, please use the following resources:

o  Security advisories and updated errata information for all releases are
   at http://www.FreeBSD.org/releases/ - always consult the ERRATA section
   for your release first as it's updated frequently.

o  The Handbook and FAQ documents are at http://www.FreeBSD.org/ and,
   along with the mailing lists, can be searched by going to
   http://www.FreeBSD.org/search/.  If the doc package has been installed
   (or fetched via pkg_add -r lang-freebsd-doc, where lang is the
   2-letter language code, e.g. en), they are also available formatted
   in /usr/local/share/doc/freebsd.

If you still have a question or problem, please take the output of
`uname -a', along with any relevant error messages, and email it
as a question to the questions@FreeBSD.org mailing list.  If you are
unfamiliar with FreeBSD's directory layout, please refer to the hier(7)
manual page.  If you are not familiar with manual pages, type `man man'.

A ce point deux choix peuvent arriver. Soit il n’y a pas de message, dans ce cas c’est terminé (migration depuis FreeBSD 8.3 et supérieur), dans ce cas c’est terminé, soit il vous est demandé de reconstruire les ports. Cette manipulation permet de compiler vos ports avec les nouvelles librairies. Si vous utilisez portupgrade

portupgrade -Raf

si vous utilisez portmaster

portmaster -af

Redémarrez une fois les ports compilés et lancez de nouveau freebsd-update install afin de nettoyer les librairies obsolètes.
