You track Microsoft System Center Configuration Manager 2007 operating system migrations by inspecting the SMS_StateMigration Server WMI Class class.

The StoreCreationDate, StoreDeletionDate, and StoreReleaseDate properties can be used to identify the current state of the migration.

To track state migrations

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Get an instance of SMS_StateMigration.
Calculate the current migration state using the StoreCreationDate, StoreDeletionDate, and StoreReleaseDate properties.

Example

The following example method enumerates through all migrations and determines whether they are in progress.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Sub MigrationState(connection)

    Dim migrations
    Dim migration
    Dim inProgress
    Dim zeroTime
        
    zeroTime = "00000000000000.000000+***"
    
    Set migrations = connection.ExecQuery( "Select * From SMS_StateMigration")

    For Each migration in Migrations
        inProgress=False
                
        If migration.StoreCreationDate<>zeroTime Then
            If migration.StoreReleaseDate = zeroTime Then
                inProgress=True
            Else If migration.StoreDeletionDate = zeroTime Then
                inProgress = True
            Else
                inProgress = false
            End If
        End If   
        Else
            inProgress=False
        End If
         
        WScript.StdOut.Write "Migration " + migration.MigrationID
        If inProgress = True Then
            Wscript.Echo " is in progress"
        Else
            WScript.Echo " is not in progress"
        End If   
    Next
    
End Sub

public void MigrationState(WqlConnectionManager connection)
{
    try
    {
        IResultObject migrations =
            connection.QueryProcessor.ExecuteQuery("Select * from SMS_StateMigration");

        string zeroTime = "00000000000000.000000+***";

        foreach (IResultObject migration in migrations)
        {
            Boolean inProgress = false;
            

            if (migration["StoreCreationDate"].DateTimeValue.Equals(zeroTime) == false)
            {
                if (migration["StoreReleaseDate"].DateTimeValue.Equals(zeroTime) == true)
                {
                    inProgress = true;
                }
                else if (migration["StoreDeletionDate"].DateTimeValue.Equals(zeroTime) == true)
                {
                    inProgress = true;
                }
                else
                {
                    inProgress = false;
                }
            }
            else
            {
                inProgress = false;
            }

            Console.Write("Migration " + migration["MigrationID"].StringValue);
            if (inProgress)
            {
                Console.WriteLine(" is in progress");
            }
            else
            {
                Console.WriteLine(" is not in progress");
            }
        }
    }
    catch (SmsException e)
    {
        Console.WriteLine("Failed while displaying migration state: " + e.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
connection	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
