Before installing CodeTwo Office 365 Migration, you need to decide on which machine you want to install it. The main factor you should take into consideration is your migration source.
In migrations from on-premises Exchange Server, the program should be installed in the source server domain – either directly on the source Exchange server or on any workstation within the source server network. Installing the program on the most powerful machine in your network or directly on the source Exchange Server will most likely work best – find out why. You do not have to install any agents on the target server or reconfigure connectors. The software accesses your source server mailboxes through Exchange Web Services (EWS) or a MAPI profile, and copies specified items to target server mailboxes via EWS. However, if you intend to migrate via MAPI, there are additional requirements you need to meet.
When you migrate from Office 365, you need to install CodeTwo Office 365 Migration on any machine with a connection to both the source and the target Office 365 environment. The program uses EWS to connect to both environments.
As for migrations from other servers (e.g. Gmail), the program can be installed on any machine with a connection to both the source and the target environment. Emails from the source will be migrated via Internet Message Access Protocol (IMAP).
The program is installed using a typical installation wizard. In the first step, click Next and you will see the license agreement that you need to accept (Fig. 1).

Next, you will be asked to specify the location where the program will be installed. The default location will display and can be left unchanged unless it's necessary to choose differently (Fig. 2.).

During the installation and configuration of the program, CodeTwo Office 365 Migration makes the following changes to your system:
Changes to operating system
The program lets you install the required .NET 4.5 Framework or MAPI Client and Collaboration Data Objects, if either of these is not already installed. The program requires also Windows PowerShell 3.0 (and one of the Windows Management Framework Core components in case of Windows Vista and Windows Server 2008).
Changes to Exchange server
The program lets you assign the required management roles (ApplicationImpersonation and View-Only Configuration) to the admin account used to configure a connection to a source Exchange server. This action grants impersonation permissions over all users in an organization.
Changes to Office 365 (Exchange Online)
The program needs to be registered in Azure Active Directory in each Office 365 tenant that will be used in the migration process. The program lets you perform the registration automatically in the source and target server connection wizard.
