# Supported version and edition upgrades (SQL Server 2017)

[!INCLUDE [SQL Server -Windows Only](../../includes/applies-to-version/sql-windows-only.md)]

You can upgrade from [!INCLUDE [sql2008-md](../../includes/sql2008-md.md)], [!INCLUDE [sql2008r2](../../includes/sql2008r2-md.md)], [!INCLUDE [ssSQL11](../../includes/sssql11-md.md)], [!INCLUDE [ssSQL14](../../includes/sssql14-md.md)], and [!INCLUDE [sssql15-md](../../includes/sssql16-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 [sssql17-md](../../includes/sssql17-md.md)].

## Pre upgrade checklist

Before upgrading from one edition of [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] to another, verify that the functionality you're currently using is supported in the edition to which you're 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 [sssql17-md](../../includes/sssql17-md.md)], you must be running a supported operating system. For more information, see [Hardware and software requirements for SQL Server 2016 and SQL Server 2017](../../sql-server/install/hardware-and-software-requirements-for-installing-sql-server.md).

Upgrade is blocked if there's a pending restart.

Upgrade is blocked if the Windows Installer service isn't running.

## Unsupported Scenarios

- Cross-version instances of [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] aren't supported. Version numbers of the [!INCLUDE [ssDE](../../includes/ssde-md.md)] components must be the same in an instance of [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)].

- [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] is only available for 64-bit platforms. Cross-platform upgrade isn't supported. You can't 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 aren't published in replication. You must re-create any logins and other user objects in `master`, `msdb`, and `model` system databases.

- You can't 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 [sssql17-md](../../includes/sssql17-md.md)], you can add features by using the [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] Setup. For more information, see [Add Features to an Instance of SQL Server (Setup)](add-features-to-an-instance-of-sql-server-setup.md).

- Failover Clusters aren't supported in WOW mode.

## Upgrades from Earlier Versions to SQL Server 2017 (14.x)

[!INCLUDE [sssql17-md](../../includes/sssql17-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 following table lists the supported upgrade scenarios from earlier versions of [!INCLUDE [ssNoVersion](../../includes/ssnoversion-md.md)] to [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)].

### SQL Server 2017 support for SQL Server 2005

This section discusses [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] support for [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)]. In [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)], you can:

- Attach a [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] database (mdf/ldf files) to [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] instance of database engine.

- Restore a [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] database to [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] instance of database engine from a backup.

- Back up a [!INCLUDE [ssASversion2005](../../includes/ssasversion2005-md.md)] cube and restore it on [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)].

When a [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] database is upgraded to [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)], the database compatibility level is changed from 90 to 100. (In [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)], valid values for the database compatibility level are 100, 110, 120, 130, and 140.) [ALTER DATABASE (Transact-SQL) compatibility level](../../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 previous list aren't supported, including but not limited to:

- Installing [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] and [!INCLUDE [sssql17-md](../../includes/sssql17-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 [sssql17-md](../../includes/sssql17-md.md)] instance.

- Configuring database mirroring between [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] and [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] instances.

- Backing up the transaction log with log shipping between [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] and [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] instances.

- Configuring linked servers between [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] and [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] instances.

- Managing a [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] instance from a [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] Management Studio.

- Attaching a [!INCLUDE [ssASversion2005](../../includes/ssasversion2005-md.md)] cube in [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] Management Studio.

- Connecting to [!INCLUDE [ssISversion2005](../../includes/ssisversion2005-md.md)] from [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] Management Studio.

- Managing a [!INCLUDE [ssISversion2005](../../includes/ssisversion2005-md.md)] service from [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)] Management Studio.

- Support for [!INCLUDE [ssVersion2005](../../includes/ssversion2005-md.md)] third party custom Integration Services components, such as execute and upgrade.

## SQL Server 2017 edition upgrade

The following table lists the supported edition upgrade scenarios in [!INCLUDE [sssql17-md](../../includes/sssql17-md.md)].

For step-by-step instructions on how to perform an edition upgrade, see [Upgrade to a different edition of SQL Server (Setup)](upgrade-downgrade-sql-server-edition-setup.md).
