ITD is in the processing of creating a test environment to prepare for the SharePoint 2013 upgrade. A Visual Upgrade to SharePoint 2010 needs to be completed prior to the SharePoint 2013 upgrade. Site collection administrators not currently upgraded to SharePoint 2010 have been notified via email. SharePoint has a feature allowing a server upgrade to happen without impacting the visual representation on existing sites. A preview option is available for the Visual Upgrade to 2010 that allows you to evaluate what SharePoint 2010 looks like on your site(s), prior to putting it into production.
