Physical topology guidance

The SQL Server topology, and your network, physical storage, and caching can significantly impact system performance. In planning your hardware, remember that this is the last version of SharePoint Products and Technologies that will run on 32-bit operating systems and databases.

ImportantImportant:

If you are using the gradual upgrade method, in order to maintain reasonable response times from the server running SQL Server, it may be necessary to increase the SQL Server resources supporting SharePoint Products and Technologies by at least a factor of two.

To learn more about the process of mapping your solution design to a farm size and set of hardware that will support your business goals, see Plan for performance and capacity (Office SharePoint Server).

Supported topologies

The following table lists the supported starting topologies in Microsoft Office SharePoint Portal Server 2003, and the supported and unsupported ending topologies when you upgrade to Microsoft Office SharePoint Server 2007.

Starting topology (SharePoint Portal Server 2003) Supported ending topology (Office SharePoint Server 2007) Unsupported ending topology (Office SharePoint Server 2007)

Single server with MSDE

Single Server with SQL Server 2005 Express Edition

Any farm

Single server with SQL Server

Single server with SQL Server

Single Server with SQL Server 2005 Express Edition, any farm

Small farm

Any farm

Single server with SQL Server 2005 Express Edition, single server with SQL Server

Medium farm

Any farm

Single server with SQL Server 2005 Express Edition, single server with SQL Server

Large farm

Any farm

Single server with SQL Server 2005 Express Edition, single server with SQL Server

NoteNote:

SQL Server 2005 Express Edition is the SQL Server 2005 replacement for MSDE.

Moving from a single server to a server farm

If you want to move from a single server to a server farm configuration, you must first migrate from MSDE or SQL Server 2005 Express Edition to SQL Server, and then add additional servers to create a server farm. You can do this by performing either of the following actions:

  • Migrate from MSDE to SQL Server 2000, and then perform your upgrade. For more information about moving from MSDE to SQL Server 2000 for SharePoint Portal Server 2003, see Migrating from MSDE to SQL Server (http://go.microsoft.com/fwlink/?LinkId=78008&clcid=0x409).

  • Upgrade (upgrading also upgrades the database from MSDE to SQL Server 2005 Express Edition), and then migrate from SQL Express to SQL Server 2005.

For more information about adding servers to a server farm, see Deployment for Office SharePoint Server 2007.

Additional configurations

There are additional constraints if you are running in any of the following configurations:

  • SharePoint Portal Server 2003 with the backwards-compatible document library features   Unsupported in Office SharePoint Server 2007. Office SharePoint Server 2007 includes new document management features that you can use instead. For more information about these features, see Planning and architecture for Office SharePoint Server 2007.

  • 32-bit versus 64-bit versions   You cannot switch between 32-bit and 64-bit versions. If you start in 32-bit, you must upgrade to 32-bit. If you need to switch from 32-bit hardware to 64-bit hardware, you should perform a database migration instead of an upgrade. For more information, see Determine upgrade approach (Office SharePoint Server).
