If the source messaging system uses Active Directory, you can use the Microsoft Active Directory Migration Tool, version 3, to migrate user objects to the target environment This can be done for Exchange 2000/2003 migrations to Exchange 2007 You can download the ADMT v3 Migration Guide from http://microsoftcom/downloads

GAL Synchronization (GALSync) is actually a component of Microsoft Identity Information Server (MIIS) and MIIS Identity Integration Feature Pack 1a An XML metabase is used to export directory information from the source directory and then import it to the target directory GALSync is specifically for Exchange to Exchange migrations The benefit of GALSync is that it can be used for extended interoperability strategies where cross-forest Exchange topologies exist Rodney R Fournier writes an excellent blog on GALSync called Identity Integration Feature Pack (IIFP) GALSync Unleashed, at http://msmvpscom/ blogs/clustering/archive/2004/10/06/15141aspx

It is possible to migrate an Exchange 2000 and/or Exchange 2003 organization to Exchange Server 2007 with third-party tools or with Microsoft tools It might be worth looking at thirdparty tools to see what benefits they can provide you before you decide to use the Microsoft tools This is especially true if you have a very large enterprise with several terabytes of data to migrate Another tricky aspect that third-party tools can help you overcome is what to do with your public folders during a migration There is no native Exchange 2007 tool for migrating public folders What s more, support for public folders has been deemphasized Some third-party migration tools are discussed at the end of this chapter Determine what data you need to migrate and then determine the best tool(s) to help you do it

To move mailbox data between two Exchange organizations, where the target organization is Exchange Server 2007, the source organizations must be Exchange 2000 or higher

5:

The tool to use is the same as the one used for the transition Move-Mailbox has the ability to bind to an Exchange 2000/2003 organization and transfer the mailbox data to an Exchange 2007 mailbox server Currently, there is no support in the Exchange Management Console (EMC) for a cross-org migration The following steps illustrate the overall process using the Exchange Management Shell (EMS) What is not shown is that GALSync is crucial to the process to ensure that mail is forwarded from the source organization to the target organization after the Move-Mailbox process is complete It would be a good idea to have GALSync set up before you embark on your migration There is no requirement for trust relationships between the forests to get the Move-Mailbox tool to work What you must have is valid credentials in both organizations, and obviously you need to run the tool from the target environment The source server permissions (Exchange 2000/2003) are as follows: Exchange Administrator Member of the Local Administrators Group The target server permissions (Exchange 2007) are as follows: Exchange Recipient Administrator Exchange Server Administrator Member of the Local Administrators group

Moving mailboxes from one organization to another organization is more complex than a typical move-mailbox command The following steps detail the additional requirements to complete the task: 1 Use the Get-Credential command to create stored usernames and passwords for Move-Mailbox to use Type in the username and password with permissions to the source organization and then do the same for the target organization, as shown next:

Part II:

2 Create a Get-Mailbox command to pull the mailboxes you want to move from the source organization Run the custom Get-Mailbox command you created to verify its results

get-mailbox -DomainController "Migration-E2K3" -Credential $SourceAdmin -Database "Migration-E2K3\First Storage Group\Mailbox Store (Migration-E2K3)"

3 Create a Move-Mailbox command that you can pipe the Get-Mailbox command to You can specify numerous parameters with the Move-Mailbox command You might want to create some test accounts to use until you get the results you are looking for

move-mailbox "TestUser" -TargetDatabase "Mailbox Database" SourceForestGlobalCatalog "Migration-E2K3startupcom" -GlobalCatalog "E2K7-MB01virtuecorpcom" -DomainController "E2K7-MB-01virtuecorpcom" -NTAccountOU "OU=MigratedUsers, DC=GK,DC=COM" -SourceForestCredential $SourceAdmin TargetForestCredential $TargetAdmin -ReportFile "C:\MigrationLogxml"

4 Combine the two into a single cmdlet 5 Confirm that you want to move all mailboxes by typing A and pressing ENTER Depending on the way you have message routing configured between the two organizations, you will either want to leave the account in the source domain or remove it Use the Get-Help Move-Mailbox -Detailed cmdlet so you can see the options available with the -SourceMailboxCleanupOptions parameter For even more examples and information on moving mailboxes between organizations, refer to the excellent blog by Paul MacKnight called, Exchange 2007 Cross Org Mailbox Migration, at http://msexchangeteamcom/archive/2006/11/02/430289aspx
