- The credentials (username and password) of an administrative user in Exchange 2010 SP1+.
- The name of any mail enabled account within Exchange 2010 SP1+.
- The URL for Autodiscovery, or the Direct Exchange Web Services URL for your Exchange 2010 SP1+ installation. Something like https://yourserver/autodiscover/autodiscover.xml.
- Setup application impersonation for Exchange 2010 SP1+.
Source Platform Prerequisites
If you're running Windows Server 2008 R2 and above, or Windows 7 and above then Powershell is installed and you dont need to do anything! If not then you will need to download it from Microsoft.
Installation is easy, just follow the steps of the installer.
Setting up Application Impersonation for Exchange
When migrating from Exchange 2010 or above, you will need to set up application impersonation in order for CloudM Migrate to access and migrate your users.
To do this, you need to open a powershell session within your Exchange server and use the following command:
New-ManagementRoleAssignment –Name "CloudMigratorImpersonation" –Role "ApplicationImpersonation" –User ADMIN
Replacing ADMIN with the email address of an administrator user on your Exchange server.
Destination Platform Prerequisites - Office 365
Setting up Application Impersonation
Alternative Application Impersonation Setup
First login to the Office 365 Exchange Admin Portal. Go to 'permissions' on the left hand side bar and click the + symbol in order to add a new role group. Enter 'CloudMigratorImpersonation' in both the Name and Description fields.
Next, click the + symbol under 'Roles', select ApplicationImpersonation, click 'add' and the click 'OK'.
Next, click the + symbol under 'Members', select your administrator user, click 'add' and then click 'OK'.
Click 'Save' and you will see the impersonation role listen in admin roles. Application impersonation is now set up.
Setting up Delegated Access
Delegated access gives a user account permission to access another. Delegated access must be set up if you are not using an Enterprise plan of Office 365
First login to the Office 365 Exchange Admin Portal. Go to 'recipients' then under 'mailboxes', double-click the user you wish to delegate access to then go to 'Mailbox Delegation' and click the '+' symbol under 'Full Access'
Next, select your administrator user, click 'add' and then click 'OK'
Click 'Save' and your administrator user now has the required access for the migration to occur, repeat this process for all users you wish to migrate.

Destination Platform Prerequisites - Google Workspace
CloudM Migrate Hosted makes migration as simple as possible. The only other prerequisite is the installation of the CloudM Migrate Hosted application. When accessing CloudM Migrate Hosted for the first time, you will be prompted to install the app, simply authorise and you are all set.
Select your configuration
Select the Exchange 2010 SP1+ configuration item.
Source Platform - Exchange 2010 SP1+
Choose Exchange 2010 SP1+ as the migration source and enter your Exchange 2010 SP1+ settings into CloudM Migrate and then click next.
- Autodiscovery Service URL – In order to connect to the correct server, autodiscovery is used to obtain the server information. Input the URL to the autodiscovery service for your domain. The value for your Microsoft Exchange server is like https://yourserver/autodiscover/autodiscover.xml.
- Admin Username – Enter the full email address of your Microsoft Exchange admin user.
- Admin Password – Enter the password of the admin user.
- Domain Name – Enter the domain name you will be migrating from. This should be the Internet domain name, not the local domain name.
- Test User Name – Enter an email address of an active user within your Microsoft Exchange system. This account is used to test connections as in most cases the admin account will not be mailbox enabled.
CloudM Migrate will now perform a small connection test to verify that the details you have entered are correct. If this fails you may have entered something incorrectly. If you are failing to resolve the issue please contact CloudM Support via the chat icon.
Destination Platform - Google Workspace
Select Google Workspace as your destination platform.
Select where you would like your data to be migrated. If you have purchased Office 365 for Business or Google Vault you may want to migrate data directly into Google Vault.
To enable Google Vault for your domain, please see the following article: http://support.google.com/vault/bin/answer.py?hl=en&answer=2584132
Enter information for your Google Workspace admin account.
- Domain Name - The domain name you will be migrating from. This should be the Internet domain name, not the local domain name.
- Admin Username - An administrator account for the domain specified, this will usually be an email address for a Super Admin.
- Service Account Email Address - Before attempting to configure CloudM Migrate, you should have created a Google Cloud platform project and created a service account for it. Input the service account's email address in this field.
- Private Key - The file path to the P12 key that was generated and downloaded when creating the OAuth service account.
If you cannot find the private key, go back to Google Cloud Platform service accounts, select your project (if not already selected), use the option button on the right of the service account and click Create Key. Select P12 and download the key file.
Once you have configured the settings, select Next. CloudM Migrate will perform a connection test against your domain to verify that everything has been entered correctly.
If your Office 365 system is brand new or for any reason the users being migrated have not been created in Office 365, CloudM Migrate can create your users for you. Simply go to advanced settings, to the user settings section and enable Create Users.
Destination Platform - Office 365
Select Office 365 as your destination platform.
Enter information for your O365 admin account.
- Admin Username - The email address of an administrator within your Office 365 environment.
- Admin Password - The password for the administrator account specified earlier.
- Domain Name - The domain name of your Office 365 environment, this might be the part after the @ in your administrator email address. If migrating from several different domains, several migrations will be needed.
- Test Username - A non-admin user who is already present in the system.
CloudM Migrate will perform a connection test against your O365 domain to verify that everything has been entered correctly.
If you are on a Small Business or Kiosk plan and need to use delegated access to migrate from Office 365 then you need to make an advanced settings change. Click Advanced Settings and under the Account Details section select Credential Method and change it to Delegated Access.
CloudM Migrate includes a number of platform configuration and provisioning options for Office 365 migration that enable advanced automation scenarios. These options can be executed during the migration process and will run as part of the migration of users' data.
There are special considerations when you need to preserve the user's domain in the target tenancy. This is because you cannot have the same domain in two Office 365 tenancies at the same time. The recommended approach to achieve this is detailed below:
- All users to be migrated in the source tenancy will have a primary SMTP email address ending in their current domain e.g. 'firstname.lastname@example.org'. Check that each of these also has at least one alias. This will be needed later to avoid having to delete users in order to stop mail going to their original mailboxes
- Provision users mailboxes in the target tenancy with their primary SMTP email addresses based on the '.onmicrosoft.com' domain.
- Configure CloudM Migrate with the target domain based on the new tenancy's '.onmicrosoft.com' domain. This will be used for both the bulk migration pass and the delta pass.
- On completion of the delta pass, all the users should have their current primary SMTP address switched to their alias. This will in-affect stop mail from being received and be the start of the mail 'down-time'.
- Remove the 'company.com' domain from all users in the source tenancy. It is essential that no objects remain assigned to this domain otherwise you will not be able to remove the domain from the tenancy.
- Remove the 'company.com' domain from the source tenancy.
- Add the 'company.com' domain to the target tenancy
- Assign the 'company.com' domain to all the users in the target tenancy and make this the primary SMTP email address
- This ends the 'mail down-time' as mail will now successfully flow to the users again in the new tenancy.
Select which users to migrate
It's now time to add which users you'd like to migrate.
When migrating from Exchange 2010 SP1+ you may be able to Get Users from the actions menu. If this option is unavailable, you can manually import users via a CSV file or simply add them individually via the plus icon.
Selecting a star next to any specific user or users will prioritize their migration. When a migration starts, threads will be assigned to any starred user so that their migration can start immediately.
At this point you can choose what to migrate for each user, when migrating from Exchange 2010 SP1+ you can migrate mail , contacts , calendars and tasks .
Enter your user's full email address within the Export Name field. If you have already created your Office 365 users then you will just need to enter their username.
To migrate files to a Google Workspace Team Drive, either select the item you wish to migrate and select 'Migrate as Team Drive' from the actions menu or specify the import type as 'TeamDrive' when adding an item. You can then specify the name or ID of the Team Drive in the 'Given Name' field. If the Team Drive specified doesn't exist then it will be created. You can use a unique ID in the 'Import Name' field to identify the Team Drive across multiple migrations. You can specify a specific folder to migrate from in the 'Documents Path' field, this will migrate only the specified folder and all subfolders. Finally, you must make sure your migrating account has organizer permissions for any Team Drives that are being migrated.
Select how much content to migrate
CloudM Migrate lets you decide how much content you'd like to migrate to your shiny new system.
If you are changing your email address as part of the migration you can verify that the domain names are correct here. You can also specify specific address replacements in the respective section of the advanced settings.
For more information on domain and address replacements, see this page.
Start your migration
We know that you may want to start your migration in the middle of the night, or over the weekend, but we don't expect you to stay up in order to do so. With CloudM Migrate you can decide to schedule exactly when you'd like the migration to occur.
Start the migration.
Review your migration results
During the migration process CloudM Migrate will report back in real time exactly who is being migrated and the items being processed. All you now need to do is sit back, relax and wait for your migration to complete.
Check the progress of your migration.
Once complete you can download a full report for your migration.
