Once the configuration is created, it will be displayed in the Configuration Overview table. Select Configure, enter a CloudM license key and select Apply to start the configuration process. 

Configure  Platform Source Settings - Google Workspace

Select Google Workspace as your Source platform.

Select Add Settings.

Basic Platform Settings

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.
• Authentication Method - Set whether to use a P12 key or a JSON key as the authentication method.
• 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. If you have selected to use a P12 key, you will need to input the service account's email address in this field.
• Private Key - The file path to the P12 or JSON 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 or JSON and download the key file.

• All Advanced Settings are set to a default value, designed to ensure that your migration will work without additional configuration. You should only edit the Advanced Settings if instructed to by CloudM Support or in a CloudM Knowledge Base article.

CloudM Migrate will perform a connection test against your Google Workspace domain to verify that everything has been entered correctly.

If your Google Workspace system is brand new or, for any reason, the users being migrated have not been created in Google Workspace, CloudM Migrate can create your users for you. Simply go to Advanced settings > User section and enable Create Users/Resources/Groups/Shared Drives.

Configure Destination Platform Settings - Microsoft 365

Basic Platform Settings

Choose Microsoft Office 365 as the migration source and enter your Microsoft Office 365 settings into CloudM Migrate and then click Next.

• All Advanced Settings are set to a default value, designed to ensure that your migration will work without additional configuration. You should only edit the Advanced Settings if instructed to by CloudM Support or in a CloudM Knowledge Base article.

Set the following settings:

• Office / Microsoft 365 Plan - Set to Office 365, Office 365 Germany or Custom, as required.
  • If you want to migrate Shared Calendar Permissions, you will need to set the Plan to Custom, as you need to provide an Autodiscovery Service URL. Direct Exchange EWS URL should not be presented.
• Authentication Method - Choose the authentication type that will be used with the server. For Microsoft 365, set to Modern.
• Domain Name - The domain name of the Exchange domain. This should be the internet domain of the Exchange system and not the local domain name.
  • This might be the part after the @ in your administrator email address. 
  • If migrating from several different domains, several migrations will be needed.
• Admin Username - The email address of a global administrator within your Microsoft 365 environment.
• Test Username - The email non-admin user who is already present in the system to test connections.
  • Specify a primary SMTP email address (or just the part before the @ symbol and the domain name will be appended). The test user must have an active mailbox.

Migrating files to Microsoft 365

If you want to migrate files to Microsoft 365, you will also need the Sharepoint Admin URL. The URL will look similar to the URL below:

• https://tenant-admin.sharepoint.com. 

To input the URL, click Advanced Settings and locate Sharepoint Admin URL under the OneDrive for Business/SharePoint settings.

Connection test

Once you have configured the Platform settings, click on Next. 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 still cannot resolve the issue, please contact CloudM Support.

Select which items to migrate

It's now time to add which items you'd like to migrate.

To add the items from that you want to migrate from your source platform to your destination platform, select Add items to migrate drop down menu and click on one of the following options:

• Get Items from source - Get a full list of all items in the source platform.
• Bulk add / import items - Upload a CSV file to bulk add users.
• Add User / Resource / Public Folder / Office (Microsoft) 365 Group / Team Site (Sharepoint Document Library) / Microsoft Team - Manually add an item of the selected item type.

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 first so that their migration can start immediately. 

At this point you can choose what to migrate for each user, you can migrate Mail, Contacts, Calendars, Tasks, Classic Sites, Notes and Channels.

Enter your user's full email address within the Export Name field. If you have already created your Microsoft 365 users, then you will just need to enter their username.

Select how much content to migrate

CloudM Migrate lets you decide how much content to migrate to your domain by specifying required date ranges. 

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.

Target Audience permissions can also be migrated but they must be replaced using Address Replacements in order to migrate successfully. If they are present on the source but not migrated to the destination platform, any items shared with it will be shared back to the source Target Audience.

Environment Scan

Environment Scan allows you to plan and prepare your migration by performing analysis of your source file and mail environment and reporting important information such as item counts, data volume, permissions, and folder depth.

Reports are produced which can be exported and analysed. Using the information provided you can estimate your migration's duration more accurately, and address any potential issues before your migration even begins.

Selecting Scope of Scan

Items

Depending on your source platform, you can choose to scan files, emails, or both sets of items.

• Leaving the Report on File Permissions setting unchecked will speed up the Environment Scan process.
• In order to include Report on File Permissions in the process, you will need to check this setting AND enable Document Sharing (or a setting related to document sharing) in the Source Platform settings. If either is not enabled, the Environment Scan will not scan or report on File Permissions.

Users

Your CloudM Migrate userlist is used to define the scope of the scan. You can choose to scan all accounts from your list, or restrict the scan to users selected for migration.

How to run an Environment Scan

After entering your source and destination server settings, populating your userlist, and configuring your settings, you will be prompted to run an environment scan. It is optional, but recommended for file platforms.

Click Start and then confirm by selecting Start Environment Scan on the pop-up box to begin the scan. CloudM Migrate will connect to your source environment and capture file and / or mail information. This can take up to several hours, depending on the amount of data present.

Once the scan completes, the data is reported on the Environment Scans page and can be exported to file, using the Export Scan Results option.

Start your migration

To begin your migration, select Start.

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.

Delta Migrations

CloudM Migrate supports delta migrations of all migration types. To run a delta migration after the first pass, simply start the migration again. Already processed mailbox items will be skipped, and file items will be checked for changes and re-migrated if updated since the previous run. More info:
