Checking System Requirements
Caution: Any computer that does not meet the requirements should be upgraded before installing Migration Manager for Exchange components.
Migration Manager for Exchange uses the following Exchange-specific agents involved in the migration process:
- Public Folder Source Agent
- Public Folder Target Agent
- Mail Source Agent
- Calendar Synchronization Agent
- Free/Busy Synchronization Agent
- Transmission Agent
- Migration Agent for Exchange
Agents work on agent host servers.
Agent host can be:
- An Exchange server itself, which is the default configuration. After you enumerate an Exchange organization all Exchange servers are registered as agent hosts for themselves.
- Another Exchange server from the same Exchange organization.
- A stand-alone server. It can be located in another forest or workgroup.
For detailed information about system requirements for agent hosts, see the Exchange Migration Agents section of the System Requirements and Access Rights.
Source Exchange 2007 Organization Considerations
- The mailbox database containing the administrator mailbox (the System Attendant mailbox used by default or custom administrator mailbox) should be mounted for each source Exchange 2007 server involved in the migration.
- The Migration Manager for Exchange console shows only those servers from source Exchange 2007 organization that host the Mailbox role. This is required because only servers with actual data are considered for migration.
Setting Up Accounts and Required Permissions
This section describes requirements for accounts working with the source Exchange servers. Migration Manager for Exchange allows you to use different administrative accounts for different purposes. Exchange data is migrated by Migration Manager for Exchange agents, which use the following accounts:
- Source Active Directory Synchronization Account
This account is used by:
- Source Agent Host Account
This account is used to install and run the Migration Manager for Exchange agents on agent host and to access the license server.
For more details, see Setting Up the Agent Host Account.
Setting Up the Source Active Directory Synchronization Account
Setting Up the Source Active Directory Synchronization Account for Exchange
This section describes how to set the required permissions for the Source Active Directory Synchronization Account. This account is used by:
- The Directory Synchronization Agent (DSA) to access the source Active Directory domain
- The Mail Source Agent (MSA) to perform mailbox switch
The required privilege level for the Source Active Directory Synchronization Account is membership in the Domain Admins group of the source domain.
Caution: If for some reason you cannot grant such privileges to the Source Active Directory Synchronization Account, and then refer to the System Requirements and Access Rights document for the list of minimal required permissions.
To grant the necessary permission to the Source Active Directory Synchronization Account, perform the following:
- On the source domain controller in the Active Directory Users and Computers snap-in, click Users, then in the right pane right-click Domain Admins and click Properties.
- Go to the Members tab, click Add and select the Source Active Directory Synchronization Account (in our example, QMM_Src_DSA).
- Close the dialog boxes by clicking OK.
Setting Up the Source Exchange Account
This section describes how to set the required permissions for the Source Exchange Account used by Migration Manager for Exchange agents. This account is used for the following:
- Working with source Exchange mailboxes and public folders (used by the Mail Source Agent, Public Folder Source Agent, and Public Folder Target Agent)
- Making the newly-created public folders mail-enabled (used by the public folder agents only: Public Folder Source Agent and Public Folder Target Agent)
- Synchronizing Calendar information (used by the Calendar Synchronization Agent)
- Synchronizing free/busy data (optional) (used by the Free/Busy Synchronization Agent)
- Switching mailboxes
The required privileges for the Source Exchange Account are as follows:
- Membership in the local Administrators group on all source Exchange servers involved in the migration. If a server is a domain controller, the account should be added to the domain local Administrators group of the domain.
- Full Control permission on the organizational units (OUs) (and their child objects) where the source synchronized objects are located.
- Full Control permission on source Exchange 2007 servers (including the Send As and Receive As permissions).
- Full Control permission on the Microsoft Exchange System Objects organizational unit in all domains in which source Exchange 2007 servers involved in public folder synchronization reside.
- Exchange Public Folder Administrator role.
To set up the Source Exchange Account, perform the steps described in the related subtopics.
NOTE: Note that the steps are given only as an example of a possible Source Exchange Account setup.
