    "PSI method is no longer supported" errors during PWA configuration and Projects migration

    Symptoms

    When migrating Projects or PWA configuration from Project Server to Project Online or Project Server 2016 as well as between two Project Online instances or if you run Projects Bulk Edit wizard you may receive the following messages:

     Project "Project Name" 
    Impacts loading error: <errinfo xmlns=""><general>
    <class name="General Unhandled Exception in _PWA.ReadProjectImpacts_">
    <error id="42" 
    name="GeneralUnhandledException" uid="5aj724ld-8469-b788-93lf-00563e66738g"
    Exception="System.NotSupportedException: 
    The ReadProjectImpacts PSI method is no longer supported
     at Microsoft.Office// 

    or

    (Exception) Exception: <errinfo xmlns=""><general><class name="General 
    Unhandled Exception in _PWA.ReadServerTimelineData_">
    <error id="42" name="GeneralUnhandledException" 
    uid="46821457-144n-d944-25k9-78471i63624w"
    Exception="System.NotSupportedException: 
    The ReadServerTimelineData PSI method is no longer supported
    at Microsoft.Office 

    or

    (Exception) Exception: <errinfo xmlns=""><general><class 
    name="General Unhandled Exception in _PWA.ReadProjectStatus_">
    <error id="42" 
    name="GeneralUnhandledException" 
    uid="b5h3j2se-4h2j-j533-56y3-24257k323647"
    Exception="System.NotSupportedException: 
    The ReadProjectStatus PSI method is no longer supported
    at Microsoft.Office

    Cause

    The above errors from the log files are caused by a reduction in available functionality in the new API provided by Microsoft in July-August 2016: 

    1. Project impacts no longer supported 

    The issue with Project impacts may appear when migrating a project from/to Project Online via Download PWA Configuration and Upload configuration to PWA wizards or Download projects to FPP files and Uploads projects from FPP files wizards.

    2. Project timelines no longer supported 

    In case you select Project Timelines in the Download PWA Configuration and Upload configuration to PWA wizards you may receive the message informing you about an error related to the problem with project timelines migration that is not supported for Project Online.

    3. Status Managers cannot be updated 

    The issue with updating the status manager may appear when exporting projects via Upload projects from the FPP files wizard. 

    Uploading Status Manager via FluentBooks is not available anymore for Project Online and Project Server 2016. 

    Solution

    1. In case you have project impacts in the project FluentBooks will log an error while migration, and it is not possible to avoid this message. 

    Please note, that projects will be downloaded and uploaded with no data loss except for project impacts. 

    2. Please uncheck the “Project timelines” checkbox while migration to avoid the error message. 

    3. Please uncheck the Update Status Manager checkbox. In this case, the task manager field will be set to the current user account, the one who performs the upload. 

    In case it is needed to set a status manager to a task, each manager would have to open the project and assign the task to themselves.
