Preparation Overview

This section provides a short overview of the main steps that should be performed to set up your Exchange 2003 organization and its environment for migration using Migration Manager for Exchange.

Setting up the Exchange 2003 organization consists of four main steps:

Checking the System Requirements

On this step make sure that your environment meets the minimal system requirements for Migration Manager for Exchange agents. For more details, see Checking System Requirements.

Setting Up Accounts and Required Permissions

On this step you should set up the accounts and required permissions for Exchange migration. There are four main types of accounts used by Migration Manager for Exchange agents:

• Active Directory Synchronization Account
  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

• Exchange Account
  This account is used by Migration Manager for Exchange agents installed on agent host to access the Exchange server.

• Active Directory Account
  This account is used by Migration Manager for Exchange agents to access the corresponding domain.

• 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.

You can simplify the setup by using a single account for all Migration Manager for Exchange processes. This account should have the permissions that are required for Migration Manager for Exchange console and all agents on every server that is involved in the migration.

For more details, see Setting Up Accounts and Required Permissions.

Preparing the Exchange Environment for Exchange Migration

On this step you should perform common environment preparations:

• Back up Exchange.
• Create the Aelita EMW Recycle Bin public folder (optional).
• Create administrator mailboxes for public folder and free/busy synchronization.
• Create administrator mailboxes for mailbox and calendar synchronization (optional)
