When you upgrade, either by using in-place upgrade or by using the
database attach upgrade method, you can choose to use Visual Upgrade.
During an in-place upgrade, you make the choice to use Visual Upgrade
as a step in the SharePoint Products Configuration Wizard. The visual
upgrade feature is not available in the SharePoint Products
Configuration Wizard if you are performing an upgrade on a stand-alone
server with built-in database. However, the Visual Upgrade feature is
available in this case from the Psconfig command-line tool. You can
then use the syntax:
psconfig.exe -cmd upgrade [–preserveolduserexperience <true|false>].
During a database attach upgrade, the choice to update to the new user
experience or stay in the old user experience is accomplished by using
• The Updateuserexperience parameter of the Mount-SPContentDatabase
Windows PowerShell cmdlet.
• The preserveolduserexperience parameter
of the addcontentdatabase Stsadm operation.
