# Supported version & edition upgrades (SQL Server 2017)

[!INCLUDE[appliesto-ss-xxxx-xxxx-xxx-md-winonly](../../includes/appliesto-ss-xxxx-xxxx-xxx-md-winonly.md)]
  
  You can upgrade from [!INCLUDE[ssKatmai](../../includes/sskatmai-md.md)], [!INCLUDE[ssKilimanjaro](../../includes/sskilimanjaro-md.md)], [!INCLUDE[ssSQL11](../../includes/sssql11-md.md)], [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)], and [!INCLUDE[sssql15-md](../../includes/sssql15-md.md)]. This article lists the supported upgrade paths from these [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] versions, and the supported edition upgrades for [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)].  
  
## Pre upgrade Checklist  
  
-   Before upgrading from one edition of [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] to another, verify that the functionality you are currently using is supported in the edition to which you are moving.  
  
-   Before upgrading [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)], enable Windows Authentication for [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Agent and verify the default configuration: that the [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Agent service account is a member of the [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] sysadmin group.  
  
-   To upgrade to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)], you must be running a supported operating system. For more information, see [Hardware and Software Requirements for Installing SQL Server](../../sql-server/install/hardware-and-software-requirements-for-installing-sql-server.md).  
  
-   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 [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] are not supported. Version numbers of the [!INCLUDE[ssDE](../../includes/ssde-md.md)] components must be the same in an instance of [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)].  
  
-   [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] is only available for 64-bit platforms. Cross-platform upgrade is not supported. You cannot upgrade a 32-bit instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] to native 64-bit using [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Setup. However, you can back up or detach databases from a 32-bit instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)], and then restore or attach them to a new instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] (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 [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)]. After you upgrade an instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)], you can add features by using the [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Setup. For more information, see [Add Features to an Instance of SQL Server (Setup)](../../database-engine/install-windows/add-features-to-an-instance-of-sql-server-2016-setup.md).  
 
-   Failover Clusters are not supported in WOW mode.  
    
## Upgrades from Earlier Versions to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)]  
 
[!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] supports upgrade from the following versions of SQL Server:
 
- SQL Server 2008 SP4 or later
- SQL Server 2008 R2 SP3 or later
- SQL Server 2012 SP2 or later
- SQL Server 2014 or later 
- SQL Server 2016 or later
 

  
> [!NOTE]  
>  To upgrade databases on [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] see [Support for 2005](#SupportFor2005).  
  
 The table below lists the supported upgrade scenarios from earlier versions of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)].

###  <a name="SupportFor2005"></a> [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Support for [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)]  
 This section discusses [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] support for [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)]. In [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)], you will be able to do the following:  
  
-   Attach a [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] database (mdf/ldf files) to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] instance of database engine.  
  
-   Restore a [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] database to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] instance of database engine from a backup.  
  
-   Back up a [!INCLUDE[ssASversion2005](../../includes/ssasversion2005-md.md)] cube and restore it on [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)].  
  
When a [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] database is upgraded to [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)], the database compatibility level will be changed from 90 to 100. (In [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)], valid values for the database compatibility level are 100, 110, 120, 130, and 140.) [ALTER DATABASE Compatibility Level &#40;Transact-SQL&#41;](../../t-sql/statements/alter-database-transact-sql-compatibility-level.md) discusses how the compatibility level change could affect [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] applications.  
  
Any scenarios not specified in the list above are not supported, including but not limited to the following:  
  
- Installing [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] and [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] on same computer (side by side).  
  
- Using a [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] instance as a member of the replication topology that involves a [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] instance.  
  
- Configuring database mirroring between [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] and [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] instances.  
  
- Backing up the transaction log with log shipping between [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] and [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] instances.  
  
- Configuring linked servers between [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] and [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] instances.  
  
- Managing a [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] instance from a [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Management Studio.  
  
- Attaching a [!INCLUDE[ssASversion2005](../../includes/ssasversion2005-md.md)] cube in [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Management Studio.  
  
- Connecting to [!INCLUDE[ssISversion2005](../../includes/ssisversion2005-md.md)] from [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Management Studio.  
  
- Managing a [!INCLUDE[ssISversion2005](../../includes/ssisversion2005-md.md)] service from [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Management Studio.  
  
- Support for [!INCLUDE[ssVersion2005](../../includes/ssversion2005-md.md)] third party custom Integration Services components, such as execute and upgrade.  
  
## [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)] Edition Upgrade  
The following table lists the supported edition upgrade scenarios in [!INCLUDE[sssqlv14-md](../../includes/sssqlv14-md.md)].
