How to Track Operating System Deployment Migrations in Configuration Manager

You track Configuration Manager operating system migrations by inspecting the SMS_StateMigration class.

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

To track state migrations

1. Set up a connection to the SMS Provider. For more information, see SMS Provider fundamentals.

2. Get an instance of SMS_StateMigration.

3. 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.
