La mise à jour de SharePoint doit être effectuée en deux étapes. Le logiciel est d’abord installé et PSCONFIG doit ensuite être exécuté pour effectuer la mise à jour de la base de données de SharePoint.

Pour déterminer si la mise à jour manuelle doit être effectué, dans une console PowerShell SharePoint, exécutez ceci :
(get-spserver $env:computername).NeedsUpgrade

Voici les étapes à suivre après la mise à jour :
1. Ouvrez une console de commande en mode administrateur (Command Prompt – cmd)
2. Allez au répertoire suivant : C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN
3. Exécutez cette commande :
PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures

Le « SharePoint configuration wizard » va démarrer et performer les tâches de configuration.
