6 Migration Manager 8.6 Introduction This is a companion document for the Migration Manager for Exchange User Guide. It does not supplant or duplicate the User Guide, but contains information that applies specifically to projects involving migration to Exchange The procedures described here are required for successful migration to an Exchange 2010 environment. For details related to all supported Exchange versions, refer to the general documentation. 4

7 Migrating to Exchange 2010 Security Configuration This section contains information about the rights and permissions necessary to perform mailbox migration to the target Exchange Server 2010 organization. First of all, refer to the Quest Migration Manager System Requirements and Access Rights document to make sure that your environment meets all the requirements to perform the migration process. Before you migrate mailboxes to Exchange Server 2010, ensure that the Exchange account (the account used for Exchange migration) has sufficient privileges to do the following: Access every mailbox within the Exchange 2010 organization Run the cmdlets performing Move mailbox operations Run the Enabl PublicFolder cmdlet to make public folders mail-enabled Access to Exchange 2010 Mailboxes For every mailbox database and its associated public folder database that is involved in migration, take the following steps: 1. In the ADSIEdit snap-in, open the Active Directory configuration partition and browse to CN=<DatabaseName>,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<ExchangeOrganizationName>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<...>,DC=<...> 2. Add the Exchange account to the CN=<DatabaseName> object and give it the Receive as permission. 3. Click Advanced and make sure that the permissions are set to This object and all child (descendant) objects. 4. In the ADSIEdit snap-in, browse to CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<ExchangeOrganizationName>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=< >,DC=< > 5. Add the Exchange account to the CN=Databases object and give it the Full Control permission. 5

8 Migration Manager Click Advanced and make sure that the permissions are set to This object and all child (descendant) objects. 7. Wait 2 hours, or restart the Information Store service twice on every target Exchange 2010 server that is involved in the migration and hosts the Mailbox role. The interval between restarts does not matter. After that, your Exchange account will have access to every Exchange 2010 mailbox in every mailbox database in your organization. You can grant the same permissions by running the following cmdlet in Exchange Management Shell: Add-ADPermission -Identity "CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<your_org_name>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<your_domain>" -User <user_name> -AccessRights GenericAll -ExtendedRights Send-As,Receive-As In some cases, the inherited Receive as permission may not work. If the Exchange account is granted the Read and Receive as permissions on the CN=Databases object and these permissions are set to This object and all child (descendant) objects, the Exchange account may not have full access to all mailboxes in the organization. To resolve this problem, you should explicitly set the Receive-as permission in the properties of Mailbox Database. Running Cmdlets to Move Mailboxes To perform Move mailbox operations, your Exchange account needs to be assigned permissions to run the following cmdlets: New-MoveRequest Get-MoveRequest Remove-MoveRequest Get-MoveRequestStatistics To assign these permissions, add this account to the Recipient Management role group in the target Exchange 2010 organization, as follows: 1. Open the Active Directory Users and Computers MMC snap-in. 2. Select the Microsoft Exchange Security Groups node. 3. In the right pane, open the properties of the Recipient Management group. 4. On the Members tab, add the account. 6

9 Migrating to Exchange 2010 Making Public Folders Mail-Enabled If a public folder is mail-enabled in the source organization, the Public Folder Target Agent needs to be able to make it mail-enabled in the target organization as well. To achieve this, assign your Exchange account permissions to run the Enable- MailPublicFolder cmdlet, as follows: 1. Add this account to the Public Folder Management role group in the target Exchange 2010 organization. 2. Give the account the Full Control permission on the CN=<ExchangeOrganizationName>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<...>,DC=<...> container. Using the Exchange Processing Wizard This section is relevant only for scenarios where Exchange migration is part of Active Directory migration. Processing Mailboxes and Public Folders OPERATION RIGHTS AND PERMISSIONS WHERE SPECIFIED Access to mailboxes and public folders Exchange impersonation (step 1) The account should be a member of the Domain Admins or Enterprise Admins group. Alternatively, if you want to avoid granting such broad privileges, make the account a member of the Organization Management and Public Folder Management roles. The ApplicationImpersonation role enables the Exchange processing user account to impersonate other users. To assign the roles to the account (<User>), run the following commands in the Exchange Management Shell: Add-RoleGroupMember "Organization Management" -Member <User> Add-RoleGroupMember "Public Folder Management" -Member <User> To enable the account (<User>) to impersonate all users in an organization, run the following in the Exchange Management Shell: New-ManagementRoleAssignment Name <AssignmentName> -Role ApplicationImpersonation User <User> See for more details related to enabling Exchange impersonation, such as limiting the scope of users. 7

10 Migration Manager 8.6 OPERATION RIGHTS AND PERMISSIONS WHERE SPECIFIED Exchange impersonation (step 2) In addition to enabling Exchange impersonation for an account, give it the necessary access privileges by granting the ms-exch- EPI-May-Impersonate extended right. To give the account (<User>) the right to impersonate all users on all Client Access Servers, run the following in the Exchange Management Shell: Set-ExchangeServer where {$_.IsClientAccessServer -eq $TRUE} ForEach-Object {Add- ADPermission -Identity $_.distinguishedname -User (Get- User -Identity <User> selectobject).identity -extendedright ms-exch-epi-impersonation} To give the account (<User>) permission to impersonate all accounts on an all MailboxDatabases, run the following in the Exchange Management Shell: Set-MailboxDatabase ForEach- Object {Add-ADPermission -Identity $_.DistinguishedName -User <User> -ExtendedRights ms-exch-epi- Impersonate} See for more details related to granting Exchange impersonation rights, such as narrowing the scope of accounts, servers and databases. Processing Mailbox and Public Folder Contents OPERATION RIGHTS AND PERMISSIONS WHERE SPECIFIED Message sending Message processing in other users' mailboxes Send As extended right. Full mailbox access rights. Run the following in the Exchange Management Shell: Add-ADPermission "Mailbox" -User <User> -Extendedrights "Send As" Run the following in the Exchange Management Shell: Add-MailboxPermission "Mailbox" - User <User> -AccessRights FullAccess 8

11 Migrating to Exchange 2010 Before You Begin This section includes the steps you need to take to prepare for migration to an Exchange 2010 organization. The Migration Manager console shows only those servers from the target Exchange 2010 organization that host the Mailbox role. Create Migration Administrator Mailboxes Migration administrator mailboxes are required for mailbox, calendar, public folder and free/busy synchronization. The Migration Manager agents will access the migrated mailboxes and public folders through an administrator mailbox that you specify. The System Attendant mailbox, which Migration Manager uses for migration to Exchange versions up to 2007, was deprecated in Exchange This means that you should create the administrator mailbox manually for every Exchange Server 2010 and specify this mailbox in the Exchange Server properties in the Migration Manager console. Synchronization of mailboxes that are hosted on Exchange 2010 servers uses the specialized Exchange Attendant component of the Migration Manager suite. During installation of shared components, Exchange Attendant is registered as a service that starts automatically. Install the Microsoft Exchange Server Messaging API Migration Manager also requires Microsoft Exchange Server Messaging API client and the latest version of Microsoft Exchange Server MAPI Client and Collaboration Data Objects to be installed on the computers where Migration Manager agents will run. Since the MAPI CDO setup package is not available for distribution, you should download it from the Microsoft Web site. For the download link, please see Microsoft Knowledge Base article After installing the API, restart the computer. 9

12 Migration Manager 8.6 Disable RPC Encryption on Exchange Servers The EncryptionRequired parameter specifies whether connections to the Exchange 2010 are required to be encrypted. The Exchange RPC Client Access service rejects unencrypted connections if this parameter is set to $true. During the migration, agents that are installed on source Exchange Server 2003 require connection to Exchange 2010 to perform some operations. Migration Manager agents create unencrypted connections, so you need to remove the RPC encryption requirement to log on to the target Exchange Server To disable the RPC encryption requirement, use the Exchange Management Shell to run the following command on all Exchange 2010 servers with mailbox databases and public folder databases that are associated with mailbox databases as well as on all Exchange 2010 servers with the Client Access Server (CAS) role installed: Set-RpcClientAccess Server <Exchange 2010 Server Name> EncryptionRequired $false Avoid Incompatible Mailboxes Exchange 2010 may create unrequested empty mailboxes for mailbox-enabled users that have no mailboxes. This behavior was not present in previous Exchange versions. The resulting mailboxes are incompatible with Migration Manager and cannot be used by during Exchange migration. Instead of relying on Exchange to create mailboxes, you should delete such automatically created mailboxes and use mailbox creation settings in your migration project. Mailboxes created by Migration Manager are fully supported. However, new Exchange 2010 mailboxes should not be deleted indiscriminately, because valid target mailboxes might be deleted in the process. The ForbidDelMailbox2010 parameter has been introduced to facilitate cleanup. Previously, the ForbidDelMailbox parameter in the mail transfer agent's INI file was the only setting responsible for preserving or removing target mailboxes whose MailboxInfo parameter did not match the same parameter in the source mailbox. The ForbidDelMailbox parameter is a precaution against the deletion of mailboxes that are in actual use in the target environment. By default, it is set to 1 so that non-matched target mailboxes are not deleted. The additional ForbidDelMailbox2010 parameter affects only Exchange 2010 target mailboxes. This parameter can have one of the following values: 0 Delete the new mailbox, but only if it is empty. 1 Let the ForbidDelMailbox parameter define what to do with the new mailbox, but only if the mailbox is empty. Otherwise, do not delete the mailbox. The ForbidDelMailbox2010 parameter is not included in the mail transfer agent's INI file by default, and its value is assumed to be 0. 10

13 Migrating to Exchange 2010 Migration Steps Currently, Exchange 2010 is supported only as the migration destination, not the source. In this release, the implementation of Exchange Server 2010 support uses the same product architecture as for migration to previous versions of Exchange Server. The main difference in migration to an Exchange 2010 organization is support for the database availability group (DAG) feature implemented in Exchange Server A database availability group is the base component of the high availability and site resilience framework built into Microsoft Exchange Server A DAG is a group of up to 16 Mailbox servers that host a set of databases and provide automatic database-level recovery from failures that affect individual servers or databases. Migration Manager for Exchange Console and migration agents detect automatically if there are mailbox databases with copies on other Exchange servers included in a DAG. Procedures such as job creation, administrator mailbox selection for all types of synchronization, and copying of mailbox content to the target mailbox database depend on the Exchange 2010 server (included in DAG) where the mailbox database is mounted. In an Exchange 2010 organization, the same set of recipients is displayed in the Migration Manager console for all active and passive database copies. This chapter does not present the migration steps in a sequence. Instead, it contains Exchange 2010-specific additions to the Migration Manager for Exchange User Guide. Register Target Exchange 2010 Organization This section complements the Registering Source and Target Organizations section in the Migration Manager for Exchange User Guide. If the target Exchange 2010 organization is added to the Migration Manager console, you can view all database copies for every Exchange Server 2010 in the tree-view irrespective of whether this server hosts an active or passive copy of the mailbox database. You can see the status (active or passive) for each copy. After you register the organization, add migration administrator mailboxes for mailbox, calendar, public folder and free/busy synchronization. Then set these mailboxes as the Migration Administrator Mailboxes in the properties of the corresponding Exchange servers or in the properties of mailbox databases. 11

14 Migration Manager 8.6 Public Folder and Free/Busy Synchronization This section complements the Public Folder Synchronization and Free/Busy Synchronization sections in the Migration Manager for Exchange User Guide. If you create a public folder or free/busy synchronization job, specify the administrator mailbox for the Exchange Server As an administrator mailbox you should specify the mailbox that is hosted on any mailbox database which has a copy on the target Exchange Server This mailbox database must be associated with the public folder database hosted on the target Exchange Server During public folder migration, if there are identically named folders in the source and target Exchange environment, then a pair of folders with the same name will appear in the target environment. Such folders are not duplicates and should not be deleted. If you encounter identically named folders after migration, consider merging them. Mailbox Migration and Calendar Synchronization This section complements the Mailbox Migration and Calendar Synchronization sections in the Migration Manager for Exchange User Guide. When you create the mailbox or calendar synchronization job with the target Exchange 2010 server specified, you can select only mailbox database that has an active copy on this Exchange 2010 server. The information about active database copies is stored in the Migration Manager console and updated during every manual refresh of the Exchange 2010 server. If the collection is created within the Mailbox or Calendar Synchronization job with certain Mailbox Database, other collections with this Mailbox Database can be created only within this job even if the active copy of this database moves to another Exchange server after creation of the first collection. By default, Mailbox Synchronization agents process mailboxes from the target Mailbox Database only if the active copy of this database is located on the target Exchange 2010 server. If the active copy of the Mailbox Database is moved to another Exchange 2010 server from the database availability group, agents stop processing mailboxes on the target server. To disable this default behavior, do either of the following: In the Migration Manager console, open the properties of the server, go to the Mail Target Agent General node, and enable the Process mailbox databases after their switchover to another server option. Specify the ProcessMailboxDBAfterSwitchover=1 parameter in the Config.ini file of the corresponding agent. After a mailbox move operation or the creation of a new Exchange 2010 mailbox during the migration process, the mailbox does not immediately become available for login. The Mail Target Agent will record login errors until the mailbox is ready (this can take up to 20 minutes). In these situations, login errors can be safely ignored. If a mailbox move request completes with an error, delete this request before the agent creates a new one. During mailbox migration, if there are identically named folders in the source mailbox and target mailbox, then a pair of folders with the same name will appear in the target mailboxes. Such folders are not duplicates and should not be deleted. If you encounter identically named folders after migration, consider merging them. 12
