1114 Part XI: Upgrading and Migrating to SharePoint Products and Technologies
Upgrading to SharePoint Portal Server 2003
If you want to move from SharePoint Portal Server 2001 to SharePoint Portal
Server 2003, consider the following changes:
■ The architecture has changed considerably. For example, you can now use
SharePoint Portal Server 2003 in a server farm configuration. Also, all site content
is now stored in the content databases instead of in the Web Storage System,
and configuration data for a server or server farm is stored in the configuration
database. For more information about the new architecture, see Part 2, “Share-
Point Products and Technologies Architecture.”
■ The security model has changed, not only concerning the security settings at
the document library level, but also the ability to secure Web Parts. For more
information about the new security model, see Chapter 6.
■ There are many new features, some changed features, such as versioning, document
profiling and metadata, and some features that no longer exist in the
new version, such as approval routing if you do not install the backwardcompatible
document library. For more information about features included in
SharePoint Portal Server 2003, see Chapter 1.
This section will detail the upgrade process, migrating Web Parts, and migrating
document library content.
The upgrade process does provide you with certain advantages, such as
the ability to link existing SharePoint Portal Server 2001 deployments into your new
navigation hierarchy and continuing to use your digital dashboard applications on
the SharePoint Portal Server 2001 machines. The upgrade process for a server running
SharePoint Portal Server 2001 is similar to the upgrade process for a server running
SharePoint Team Services. You will first have to decide how you wish to use the
updated features. In most cases, the SQL Server content store is a better choice
because the SQL Server content store provides fast database performance, manageability,
scalability, and the familiar SQL Server administrator tools. However, if you
wish to retain the ability of multiple document profiles per document library folder
as well as the complex routing and approval workflow features of the document
store from SharePoint Portal Server 2001, you will need to install the backwardcompatible
document library. Also, you will need to consider reviewing any application
you have developed that integrates with SharePoint Portal Server 2001 and uses
the Publishing and Knowledge Management Collaboration Data Objects (PKMCDO)
interface to the Web Storage System.
If you decide that you wish to install the backward-compatible document
library, to host the documents from your SharePoint Portal Server 2001 installation,
you will need to run the in-place upgrade process. This process converts and retains
the contents of the SharePoint Portal Server 2001 Web Storage System to the Share-
Point Portal Server 2003 backward-compatible document library. If you do not wish
