With Office Communications Server 2007 R2, the default container for Office Communications Server global settings is the Configuration container. In previous versions, the default container was System container of the root domain.

Although storing global settings in the System container has advantages, such as faster replication and fewer replicated copies, in centralized topologies, this approach might not perform as well in geographically distributed topologies if root domain availability is insufficient. If you deployed Office Communications Server 2007 with global settings stored in the System container and you experience performance problems, such as long service start time or long replication delays when you manage global settings, we recommend that you move global settings from the System container to the Configuration container. The Microsoft Office Communications Server 2007 Global Settings Migration Tool is designed for this purpose. This tool is available at the Microsoft Download Center at http://go.microsoft.com/fwlink/?LinkId=137424 .

Important:
If you decide to move your global settings to the Configuration container, you must do so before you upgrade to the Office Communications Server 2007 R2 Active Directory schema. The Global Settings Migration Tool will not work if the new Active Directory schema extensions have been installed.

The procedure for moving the global settings is as follows. These steps are described in detail in the following sections. You must be logged on as a member of the EnterpriseAdminsto perform this procedure.

Important:
In the following procedure, you must use the Office Communications Server 2007 snap-in and command line tools. Do not use the Office Communications Server 2007 R2 tools.

At the end of each step, full replication of the Active Directory Domain Services must be complete before you proceed to the next step. Depending on the topology and replication configuration, full replication can take anywhere from minutes to days.
Important:
After you begin to migrate global settings, do not attempt to move or modify users until the final step in the process is complete.

To move global settings to the Configuration container

  1. Copy the Tree Structureto the Configuration container. At a command prompt, type the following command, and then press RETURN:

    cscript MigrateOcsGlobalSettings.vbs /Action:MigrateGlobalSettingsTree

    Important:
    Wait until replication completes before proceeding to the next step.

  2. Copy Global Settings Attributes. At a command prompt, type the following command, and then press RETURN:

    Cscript MigrateOcsGlobalSettings.vbs /Action:MigrateGlobalSettingsProperties

    Important:
    Wait until replication completes before proceeding to the next step.

  3. Run Forest Preparation.

    Important:
    You must use the Office Communications Server 2007 version of LcsCmd.exe to run this step. Do not use the Office Communications Server 2007 R2 version of LcsCmd.exe or the Office Communications Server Prep Forest wizard for this step. The wizard will show that the forest is already prepared, although the access control entries (ACEs) are not in the new container yet.
    Important:
    Wait for the global settings tree to replicate to most forest global catalogs before proceeding to the next step.

    At a command prompt, type the following command, and then press RETURN:

    LcsCmd /Forest /Action:ForestPrep /global:configuration

  4. Update DN References to the Global Settings Tree. At a command prompt, type the following command, and then press RETURN:

    cscript MigrateOcsGlobalSettings.vbs /Action: MigrateServerDnReferences /SearchBaseDN:<server search base DN>

    Where server search base DNis the migration scope for servers.

  5. Update msRTCSIP-PrimaryHomeServer DN Referencesfor User, Contact, and inetOrgPerson objects. At a command prompt, type the following command, and then press RETURN:

    cscript MigrateOcsGlobalSettings.vbs /Action: MigrateUserDnReferences /SearchBaseDN:<user search base DN>

    Where server search base DNis the migration scope for users.

  6. Use the Office Communications Server 2007 snap-in to restart the Office Communications Server services, and then Verify That Migration Was Successful.

  7. Remove Global Settings Tree from the System Containerin the root domain. At a command prompt, type the following command, and then press RETURN:

    cscript MigrateOcsGlobalSettings.vbs /Action: DeleteSystemGlobalSettingsTree
