Review supported and unsupported upgrade paths

Updated: March 5, 2009

Applies To: Office SharePoint Server 2007

In this article:

This article helps you understand which upgrade paths are supported or unsupported for the SharePoint Products and Technologies.

In general, you can upgrade between versions of the same product or technology (such as Windows SharePoint Services 2.0 to Windows SharePoint Services 3.0 or Microsoft Office SharePoint Portal Server 2003 Service Pack 2 to Microsoft Office SharePoint Server 2007), but you cannot attempt to run more than one version of more than one of these technologies together on the same hardware, such as both Windows SharePoint Services 3.0 and SharePoint Portal Server 2003.

Some of the SharePoint Products and Technologies can co-exist with each other (such as Office SharePoint Server 2007 and Microsoft Office Project Server 2007), or be upgraded across product or version (such as from Windows SharePoint Services 3.0 to Office SharePoint Server 2007). For more information on supported methods of upgrade both across versions and across products in the SharePoint Products and Technologies, see the Version to Version Supported Upgrade Paths (http://go.microsoft.com/fwlink/?LinkId=93573&clcid=0x409) article on the Microsoft SharePoint Products and Technologies Team Blog.

For more information on how to choose between upgrade approaches, such as in-place upgrade, gradual upgrade, or database migration, see Determine upgrade approach (Office SharePoint Server).

Supported paths

The following upgrade paths are supported for moving between versions of the SharePoint Products and Technologies:

  • Upgrading from Windows SharePoint Services 2.0 Service Pack 2 (SP2) to Windows SharePoint Services 3.0.

  • Upgrading from Windows SharePoint Services 2.0 SP2 to Windows SharePoint Services 3.0, and then upgrading to Office SharePoint Server 2007.

  • Upgrading from Windows SharePoint Services 2.0 SP2 directly to Office SharePoint Server 2007 by using database migration.

  • Upgrading from SharePoint Portal Server 2003 SP2 to Office SharePoint Server 2007.

  • Migrating from Microsoft Content Management Server 2002 to Office SharePoint Server 2007.

Unsupported paths

The following upgrade paths are not supported:

  • Upgrading from Windows SharePoint Services 2.0 SP2 directly to Office SharePoint Server 2007 by using in-place or gradual upgrade.

    If you want to upgrade from Windows SharePoint Services 2.0 SP2 directly to Office SharePoint Server 2007, you must use the database migration approach. For more information, see Chapter overview: Deploy a new farm, then migrate databases (Office SharePoint Server).

  • Upgrading from SharePoint Portal Server 2003 to Windows SharePoint Services 3.0.

    The only valid upgrade path for SharePoint Portal Server 2003 is to Office SharePoint Server 2007.

  • Upgrading from Windows SharePoint Services 2.0, SP2 to Windows SharePoint Services 3.0 in a SharePoint Portal Server 2003 environment, leaving the SharePoint Portal Server 2003 environment as is.

    You cannot run more than one version of more than one of the SharePoint Products and Technologies together on the same hardware. If your goal is to upgrade only your collaboration sites from your SharePoint Portal Server 2003 environment, and not upgrade your portal sites, then you should create a separate Windows SharePoint Services 3.0 environment and use the database migration approach to move the content databases for your collaboration sites to that new environment, leaving the SharePoint Portal Server 2003 environment as is. Be sure to migrate only collaboration sites; the migration and upgrade process for Windows SharePoint Services 3.0 cannot upgrade portal sites. Otherwise, you should upgrade the entire environment to Office SharePoint Server 2007 using one of the recommended methods previously. Upgrading the entire environment gives you all the functionality of Office SharePoint Server 2007 for your upgraded portal sites, and all of the collaboration features of Windows SharePoint Services 3.0 for your collaboration sites.
