Migration Manager for Exchange 8.15 - Source and Target Exchange 2003 Environment Preparation

Checking System Requirements

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 (for source Exchange environment only)
• Mail Target Agent (for target Exchange environment only)
• Calendar Synchronization Agent
• Free/Busy Synchronization Agent
• Transmission Agent
• Migration Agent for Exchange

Agents work on agent host servers.

Agent host can be:

1. 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.
2. Another Exchange server from the same Exchange organization.
3. 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.

Setting Up Accounts and Required Permissions

This section describes requirements for accounts working with the 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:

  This account is used by:
  1. The Directory Synchronization Agent (DSA) to access the corresponding Active Directory domain
  2. The Mail Source Agent (MSA) to perform mailbox switch

For more details, see Setting Up the Active Directory Synchronization Account.

• Exchange Account
  This account is used by Migration Manager for Exchange agents installed on agent host to access the Exchange server.
  For more details, see Setting Up the Exchange Account.

• Active Directory Account
  This account is used by Migration Manager for Exchange agents to access the corresponding domain.
  For more details, see Setting Up the Active Directory Account.

• Agent Host Account

  For more details, see Setting Up Agent Host Account.

Setting Up the Active Directory Synchronization Account

This section describes how to set the required permissions for the Active Directory Synchronization Account. This account is used by:

In the source Exchange 2003 environment

• Working with the source Exchange mailboxes and public folders (used by the Mail Source/Target 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)
