Source Exchange 2010 Environment Preparation

Follow the steps that are described in the Preparation Checklist topic to prepare your Exchange 2010 organization and its environment for being the source organization in the Exchange migration process conducted by Migration Manager for Exchange.

On some of steps you may need to coordinate the setup process with the administrator of the target Exchange organization.

Preparation Overview

This section provides a short overview of the main steps that should be performed to set up your source Exchange 2010 organization and its environment for migration using Migration Manager for Exchange. These steps are described in detail below.

Setting up the source Exchange 2010 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 detail, 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:

  • Source Active Directory Synchronization Account

    This account is used by:

    1. The Directory Synchronization Agent (DSA) to access the source Active Directory domain
    2. The Mail Source Agent (MSA) to perform mailbox switch
  • Source Exchange Account
    This account is used by Migration Manager for Exchange agents installed on agent host to access the source Exchange server.
  • Source Active Directory Account
    This account is used by Migration Manager for Exchange agents to access the source domain.
  • 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.

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 Source 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)
  • Create custom throttling policies
  • Install Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 version 6.5.8353.0 or later.

For more detail, seePreparing the Source Exchange Environment for Exchange Migration.

Setting Up Connection with the Target Exchange Organization Using SMTP Connectors

On this fourth step you should set up the connection with the target Exchange organization using SMTP connectors. This task consists of three subtasks given below:

  1. Setting up the source Exchange 2010 organization for Internet mail flow between source and target Exchange organizations
  2. Configuring source DNS server for mail forwarding
  3. Testing the SMTP connectors (optional)

For more details, see Setting Up Connection with the Target Exchange Organization Using SMTP Connectors.
