|Feature||Why Changed||Migration Plan|
|Visual upgrade||The visual upgrade feature is replaced with deferred site collection upgrade||Need to Migrate from MOSS 2007 to SharePoint 2010
Then from SharePoint 2010 to Share 2013
|Document Workspace site template||The scenario of collaborating on a document is now provided by the Team Site site template. The Document Workspace site template was removed from SharePoint 2013 to simplify the list of templates that are available when a user creates a new site collection.||Will continue to operate in SharePoint 2013. This will be removed completely from the next major release of SharePoint|
|Personalization Site site template||Not widely used site template||Will continue to operate in SharePoint 2013. This will be removed completely from the next major release of SharePoint|
|Meeting Workspace site templates||SharePoint 2013 and Office 2013 provide other features that support meetings and collaboration. For example, you can use Lync to conduct live meetings, OneNote to take notes during meetings, and a SharePoint team site or My Site to store shared meeting notes.||Will continue to operate in SharePoint 2013. This will be removed completely from the next major release of SharePoint|
|Group Work site template and Group Work solution||Not widely used site template|
|Visio Process Repository site template||Not widely used site template|
|Imaging Web service||Not widely used site template||All the functionality of the Imaging Web service is available through the client-side object model (CSOM). The CSOM provides client-side applications with access to a subset of the SharePoint Foundation server object model, including core objects such as site collections, sites, lists, and list items. Also, Web Distributed Authoring and Versioning (WebDAV) provides clients with key functionality of the Imaging Web service (for example, upload, download, and rename).|
|Excel Services — Can’t edit workbooks in the browser that have external data connections||This is a design limitation in SharePoint 2013||You can still refresh these workbooks in the Excel client program. Additionally, a service application administrator can configure that workbooks are viewed in SharePoint 2013 instead of Office Web Apps Server.|
|Search capabilities||The search capabilities of SharePoint Foundation 2013 have changed, and are now based on the same search implementation as SharePoint Server. This provides many improvements, but also means that the search configuration is very different.||No migration of search settings is supported.|
|Search Query web service||The Search Query web service is deprecated because the client object model (CSOM) and a new REST-based web service are available for developing Office-wide extensibility scenarios. The CSOM exposes the same functionality as the Search Query web service, and a larger set of functionality for stand-alone client applications.||Change custom search solutions to use the CSOM or REST-based web service instead of using the Search Query web service.|
|Search RSS and search from Windows||Most RSS readers that are available do not support claims authentication. In SharePoint 2013, claims authentication is the default authentication model. By using claims authentication, RSS readers work while the authentication cookie is cached. However, after the cookie expires, RSS readers cannot refresh their authentication, and so they stop working.||After migrating a site to SharePoint 2013, you can create search-based alerts to be notified of changes to search results. You can also create a custom RSS feed in SharePoint document libraries, by using the UX extensibility platform.|
|SharePoint Search SQL syntax|| In SharePoint Server 2010, you could construct complex search queries by using SQL syntax.
Search in SharePoint 2013 supports FAST Query Language (FQL) syntax and Keyword Query Language (KQL) syntax for custom search solutions.
The core search architecture has changed in SharePoint 2013, and the SQL syntax is no longer supported.
|Change current search solutions to use either the KQL syntax or FQL syntax for queries|
|Shallow search refiners||The shallow search refiners are replaced with an improved implementation of deep search refiners.||No specific migration steps are necessary|
|FAST Search database connector||The FAST Search database connector is not supported in SharePoint 2013.
The connector framework for SharePoint 2013 is combined with the BCS framework and the Business Data Catalog connectors.
|Replace the FAST Search database connector with the Business Data Catalog-based indexing connectors in the BCS framework.|
