Undo Visual Upgrade in SharePoint 2010

Hi friends, you might have performed visual upgrade in SharePoint 2010 after upgrading your SharePoint farm from MOSS 2007. If you want to revert the user interface back to MOSS 2007 style, there isn't any link in Site Settings as you did visual upgrade. To do this for one web site, you can run PowerShell command below.

 Go to Start menu, click All Programs.


Click Microsoft SharePoint 2010 Products.


Click SharePoint 2010 Management Shell.


At the Windows PowerShell command prompt, type the following command:

$Web=Get-SPWeb http://yoururl/yourweb
$Web.UIVersion=3
$Web.UIVersionConfigurationEnabled=$true
$Web.update()

I will be posting further about this topic.

Thanks

To revert a specific site in a site collection to the previous UI, at the Windows PowerShell command prompt, type the following command:

Get-SPSite http://machinename/sites/V3UI | Get-SPWeb "webname" | Foreach{$_.UIVersionConfigurationEnabled=1;$_.UIVersion=3;$_.Update();}

To reverts all sites in a site collection to the previous user interface, at the Windows PowerShell command prompt, type the following command:

Get-SPSite http://machinename/sites/V3UI | Foreach{$_.UIVersionConfigurationEnabled=1;$_.UIVersion=3;$_.Update();}

To force with Visual Upgrade

$webapp = Get-SPWebApplication http://sitename
foreach ($s in $webapp.sites)
{$s.VisualUpgradeWebs() }

To view status of current user interface by using Windows PowerShell

$sc = Get-SPSite http://machinename/sites/collectionname; $sc.GetVisualReport() | Format-Table
