Search-first migration from FAST Search Server for SharePoint 2010 to SharePoint Server 2013

SharePoint 2013

Published: March 19, 2013

This article describes how to perform a search-first migration from Microsoft FAST Search Server 2010 for SharePoint to SharePoint Server 2013.

Applies to:  SharePoint Server 2013 | FAST Search Server 2010 for SharePoint 

Introduction to search-first migration (SharePoint Server 2013)

Upgrading from FAST Search Server 2010 for SharePoint to SharePoint Server 2013 provides significant improvements in enterprise search capabilities. However, policy or resource constraints in an organization may pose challenges that prevent or postpone a complete upgrade. Even if your organization is not ready to perform a complete upgrade from FAST Search Server 2010 for SharePoint, you can take advantage of new SharePoint Server 2013 search capabilities by performing a search-first migration.

To be able to configure and use certain features, such as Result sources, you must perform a full migration of your farm from FAST Search Server 2010 for SharePoint to SharePoint Server 2013.

When you've completed a search-first migration, you run your system in "mixed mode." Mixed mode is when a FAST Search Server 2010 for SharePoint Enterprise Search Center is used to consume SharePoint Server 2013 search. Users can still use the FAST Search Server 2010 for SharePoint Enterprise Search Center, but queries will be sent to the SharePoint Server 2013 index.

Running your system in mixed mode means that you do not upgrade the content of your farm or the site collection to SharePoint Server 2013. The FAST Search Server 2010 for SharePoint farm can continue to provide other FAST Search Server 2010 for SharePoint functionality for your organization. FAST Search Server 2010 for SharePoint features, such as content databases and the Business Data Catalog, are not migrated or upgraded as part of a search-first migration. Functionality that is not related to search does not have to be configured in the new SharePoint Server 2013 farm. Some FAST Search Server 2010 for SharePoint features will only work in backward compatibility mode.

Your organization can complete the product upgrade at any time.

note Note:

Due to the many architectural changes between FAST Search Server 2010 for SharePoint and SharePoint Server 2013, not all configurations and features can be migrated. If you are unsure of the implications of a migration from FAST Search Server 2010 for SharePoint to SharePoint Server 2013, we strongly recommend that you contact a trusted Microsoft partner or Microsoft Consulting Services for guidance.

Supported migration path

Search-first migration supports only the partial migration of search capabilities from a FAST Search Server 2010 for SharePoint farm to a SharePoint Server 2013 farm.

High-level search-first migration steps

1.Migrate settings. 2. Migrate search settings to new SSA. Using SharePoint Server 2013 SSA, index content from SharePoint Server 2010 farms. Connect SharePoint Server 2010 Search Center to SharePoint Server 2013. Consume search. 3. Disconnect servers.

Make sure that you have a FAST Search Server 2010 for SharePoint production farm with at least one Search service application. This production farm must also be configured and operating with enterprise search functionality.

To complete a search-first migration:

  1. Install SharePoint Server 2013 on a single server with an additional dedicated SQL Server.

    See also: Install SharePoint 2013 on a single server with SQL Server

  2. On the SharePoint Server 2013 SQL Server, install:

    • Microsoft .NET Framework version 4.5

    • PowerShell Snapins for SQL Server

  3. On the FAST Search Server 2010 for SharePoint farm, back up these databases:

    • FAST Search Administration database

    • FAST Content Search Service Application database

    • FAST Query Search Service Application database

  4. Download the search-first migration scripts from TechNet Gallery. For details and guidance on using these scripts, refer to the PDF included in the download package.

    • Edit the environment variables in the scripts.

    • Save and copy the scripts to the SQL Server and to the SharePoint Server 2013 server.

  5. On the SharePoint Server 2013 SQL Server, run the search-first migration scripts.

  6. On the SharePoint Server 2013 server, run the search-first migration scripts.

  7. Build out the new SharePoint Server 2013 farm topology. For instructions on how to do this, see Manage the search topology in SharePoint Server 2013.

  8. On the SharePoint Server 2013, start crawling.

note Note:

For information about limitations, see Features with limitations.

  • If the migration is complete, that is to say, if both content source and front end are upgraded to SharePoint Server 2013, Result sources replace the Scopes feature.

Features with limitations

When you run SharePoint Server 2013 in mixed mode, certain features will function with limitations. You’ll have to use manual workarounds for these features to work correctly. The following sections explain:

Limitations when you migrate from FAST Search Server 2010 for SharePoint Search Center to SharePoint Server 2013

Feature name Limitation

Document previews

Document previews is not a backward compatible feature because SharePoint Server 2013 can't render Document previews that are generated by a FAST Search Server 2010 for SharePoint content farm.

Duplicate documents link in the search results page

The Duplicate documents link is displayed in the search results page. However, it displays no duplicate documents when it is clicked. To avoid confusion, you can disable this link by editing the XSLT file in the Core results Web Part.

Author refiner

The Author managed property was redefined and replaced by the managed property DisplayAuthor in SharePoint Server 2013. The migration script migrates the Author refiner without changing it. To make the Author refiner work, you must manually edit the XSLT in the refinement panel, and change the Author to DisplayAuthor.

Site refiner

In SharePoint Server 2013, the managed property SPSiteURL is used to populate the site refiner. If there are problems with the site refiner after migration, verify that:

  • The properties Basic:4 and ows_SPSiteURL are mapped to SPSiteURL.

  • RespectPriority of SPSiteUrl is set to true.

See also FAST Search Server 2010 for SharePoint deprecated features.

Limitations after a full migration to SharePoint Server 2013

Feature name Limitation

Best Bets

SharePoint Server 2013 does not support Best Bets. The feature’s been replaced by query rules. Best Bets are not automatically converted to query rules, so you have to create new query rules.

Front end

It isn’t possible to automatically upgrade the FAST Search Server 2010 for SharePoint front end.
