fix
If something occurs during the mailbox migration that prevents some or all of the messages from being migrated, you may clear the LastMigration time from the database, run the post migration task "Synchronize and Update Migrated Mailboxes" in an attempt to bring over the missing messages.  The examples below assume that the database name is "EMA", which is the default name for the Exchange Migrator database.

Using SQL Query Analyzer or OSQL command line, the LastMigration time can be cleared as follows:

  1. To remove the LastMigration time for an entire project:

    Running the following query removes the LastMigration time for the given project number (idProject).  The idProject number for your particular project can be located by viewing the information in the Project table.  To check the idProject number using SQL Server Enterprise Manager, expand the EMA database, highlight tables, right click the Project table, and select return all rows.  It is critical that you specify the correct 'idProject' number to ensure the LastMigration value is removed for the desired project.  Specify the project number in the query below.

    USE EMA
    UPDATE Projectstatus
    SET projectstatus.LastMigration = ''
    FROM ProjectStatus, MigrationInfo
    WHERE (idProject = 'idProject_Number')

  2. To remove the LastMigration time for a group of mailboxes based on the target alias names:

    Specify the target alias names in the query below.

    USE EMA
    UPDATE Projectstatus
    SET projectstatus.LastMigration = ''
    FROM ProjectStatus, MigrationInfo
    WHERE MigrationInfo.idObject = ProjectStatus.idObjectID AND TargetAlias IN ('TargetAlias1', 'TargetAlias2')

  3. To remove the LastMigration time for a single mailbox based on the target alias name:

    Specify the target alias name in the query below.

    USE EMA
    UPDATE Projectstatus
    SET projectstatus.LastMigration = ''
    FROM ProjectStatus, MigrationInfo
    WHERE MigrationInfo.idObject = ProjectStatus.idObjectID AND TargetAlias = 'TargetAlias1'



note
If you are using MSDE, start an OSQL command line as follows:

  1. Access a command prompt and enter the following:

    OSQL -U sa -P insert_sa_password_here

  2. You will then get a prompt that looks like '1>'. At this time, you can continue with the commands as they appear in this article. At the end of each command line hit the Enter/Return key. Once you have completed the above commands, add a line that says GO and press Enter/Return.


note
CAUTION: This SQL Query directly accesses your database and updates/deletes data. If the query is performed incorrectly it can cause irreparable harm to the database and may result in loss of data. If you are unfamiliar with SQL or how to run a SQL Query please contact NetIQ Technical Support directly.
