Supported Version and Edition Upgrades
You can upgrade from SQL Server 2008, and SQL Server 2008 R2, and SQL Server 2012. This topic lists the supported upgrade paths from these SQL Server versions, and the supported edition upgrades for SQL Server 2014.
Pre upgrade Checklist
Before upgrading from one edition of SQL Server 2014 to another, verify that the functionality you are currently using is supported in the edition to which you are moving.
Before upgrading SQL Server, enable Windows Authentication for SQL Server Agent and verify the default configuration: that the SQL Server Agent service account is a member of the SQL Server sysadmin group.
To upgrade to SQL Server 2014, you must be running a supported operating system. For more information, see Hardware and Software Requirements for Installing SQL Server 2014.
Upgrade will be blocked if there is a pending restart.
Upgrade will be blocked if the Windows Installer service is not running.
Unsupported Scenarios
Cross-version instances of SQL Server 2014 are not supported. Version numbers of the Database Engine, Analysis Services, and Reporting Services components must be the same in an instance of SQL Server 2014.
Cross-platform upgrade is not supported. You cannot upgrade a 32-bit instance of SQL Server to native 64-bit using SQL Server Setup. However, you can back up or detach databases from a 32-bit instance of SQL Server, and then restore or attach them to a new instance of SQL Server (64-bit) if the databases are not published in replication. You must re-create any logins and other user objects in master, msdb, and model system databases.
You cannot add new features during the upgrade of your existing instance of SQL Server. After you upgrade an instance of SQL Server to SQL Server 2014, you can add features by using the SQL Server 2014 Setup. For more information, see Add Features to an Instance of SQL Server 2014 (Setup).
Failover Clusters are not supported in WOW mode.
Upgrade from an Evaluation edition of a previous SQL Server version is not supported.
Upgrades from Earlier Versions to SQL Server 2014
Note
Support for SQL Server 2005 is described in more detail in the next section, 'SQL Server 2014 support for SQL Server 2005'.
SQL Server 32-bit editions can be upgraded to SQL Server 2014 on the 32-bit subsystem (WOW64) of a 64-bit server.
SQL Server 64-bit versions can be upgraded to SQL Server 2014 64-bit server only.
Note
When you upgrade to SQL Server 2014 from a prior version of SQL Server Enterprise edition, choose between Enterprise Edition: Core-based Licensing and Enterprise Edition. These Enterprise editions differ only with respect to the licensing modes and the maximum number of cores supported. For more information, see Compute Capacity Limits by Edition of SQL Server.
SQL Server 2014 supports upgrade from the following versions of SQL Server:
SQL Server 2005 SP4 or later
SQL Server 2008 SP3 or later
SQL Server 2008 R2 SP2 or later
SQL Server 2012 SP1 or later

SQL Server 2014 Support for SQL Server 2005
This section discusses SQL Server 2014 support for SQL Server 2005. In SQL Server 2014, you will be able to do the following:
Upgrade a SQL Server 2005 instance of database engine to SQL Server 2014 by running SQL Server 2014 setup using the installation wizard or from the command prompt.
Attach a SQL Server 2005 database (mdf/ldf files) to SQL Server 2014 instance of database engine.
Restore a SQL Server 2005 database to SQL Server 2014 instance of database engine from a backup.
Upgrade a SQL Server 2005 Integration Services (SSIS) package to SQL Server 2014. Execute packages with automatic-in-place upgrade.
Upgrade a SQL Server 2005 Analysis Services (SSAS) to SQL Server 2014 by running SQL Server 2014 setup.
Back up a SQL Server 2005 Analysis Services (SSAS) cube and restoring on SQL Server 2014.
Upgrade SQL Server 2005 Reporting Services (SSRS) to SQL Server 2014 by running SQL Server 2014 setup.
Connect to SQL Server 2005by using SQL Server Profiler 2014.
When a SQL Server 2005 database is upgraded to SQL Server 2014, the database compatibility level will be changed from 90 to 100. (In SQL Server 2014, valid values for the database compatibility level are 100, 110 and 120.) ALTER DATABASE Compatibility Level (Transact-SQL) discusses how the compatibility level change could affect SQL Server applications.
Any scenarios not specified in the list above are not supported, including but not limited to the following:
Installing SQL Server 2005 and SQL Server 2014 on same computer (side by side).
Using a SQL Server 2005 instance as a member of the replication topology that involves a SQL Server 2014 instance.
Configuring database mirroring between SQL Server 2014 and SQL Server 2005 instances.
Backing up the transaction log with log shipping between SQL Server 2014 and SQL Server 2005 instances.
Configuring linked servers between SQL Server 2014 and SQL Server 2005 instances.
Managing a SQL Server 2005 instance from a SQL Server 2014 Management Studio.
Attaching a SQL Server 2005 Analysis Services (SSAS) cube in SQL Server 2014 Management Studio.
Connecting to SQL Server 2005 Integration Services (SSIS) from SQL Server 2014 Management Studio.
Managing a SQL Server 2005 Integration Services (SSIS) service from SQL Server 2014 Management Studio.
