In this article:

When determining a migration path, it is important to consider the compatibility of Project Professional with Microsoft Office Project Server 2007 and the file-format compatibility between versions of Project Professional.

To determine cross-version compatibility between Project Professional and Project Server versions, refer to the chart below.

 

This client version Only connects to this server version

Project 2000

Project Central

Project Standard 2002

Project Server 2002

Project Professional 2002

Project Server 2002, Project Server 2003

NoteNote:
For more information about connecting to Project Server 2003, see the Microsoft Knowledge Base article 885115: How to allow Microsoft Project Professional 2002 users to connect to Project Server 2003 (http://go.microsoft.com/fwlink/?LinkId=120253).

Project Professional 2003

Project Server 2003, Project Server 2002

Project Professional 2007

Project Server 2007

ImportantImportant:
Project Professional 2003 is not compatible with Office Project Server 2007. Similarly, Microsoft Office Project Professional 2007 is not compatible with Project Server 2003.

The main reason for the incompatibility between these versions is a fundamental update of the client-to-server communication protocol. Project Server 2003 uses ODBC to open or save enterprise projects from Project Professional 2003. Office Project Server 2007 uses Web services. This change enables Office Project Professional 2007 to connect to the server over a WAN by using low bandwidth HTTP/HTTPS connections, and it also provides a smooth experience for users whether they are online or offline.

Another reason for the incompatibility is that the database schema has undergone significant changes for Office Project Professional 2007.

The following scenarios are supported in order to work around the compatibility limitation:

  • Installing Project Professional 2003 and Office Project Professional 2007 side-by-side on the same computer. This side-by-side support extends to other project components like Project ActiveX controls and Outlook add-ins as well.

    NoteNote:
    Office Project Professional 2007 should be installed after Project Professional 2003 for all functionality to work correctly.
  • Installing Project Server 2003 and Office Project Server 2007 on the same server (Windows SharePoint Services 2.0 and Windows SharePoint Services 3.0 can be installed side-by-side on the same computer)

Project 2007 clients (Including both Professional and Standard versions):

  • Can open .mpp files for:

    • Project 98

    • Project 2000

    • Project 2002

    • Project 2003 (Professional and Standard versions)

  • Can save .mpp files to the following file formats:

    • Project 2000

    • Project 2002

    • Project 2003

  • Can open from an existing ODBC data source.

  • Cannot save to an ODBC data source.

Project 2003 (Professional and Standard versions):

  • Cannot open a Project 2007 .mpp file.
