1. Introduction

Google Shared Drives (Team Drives) can be migrated as part of your entire migration plan or as an independent project, depending on your business needs. You can migrate your Google Shared Drives to Microsoft Teams or to SharePoint sites.

1.1. What is migrated

You will find the list of what can be migrated on this page: Google Shared Drives to Office 365 Groups.

1.2. Performance & Security

For more information about security, please refer to this article.

For more information about migration performance, please refer to this article.

1.3. License Management

Cloudiway platform automatically assigns the licenses, for more details regarding the license management, check out this page.

1.4. Delta Passes

Delta migration is a Cloudiway functionality that allows you to migrate incrementally. Changes are migrated during delta passes. Deletions are not propagated.

1.5. Support

Although we provide support for our own products, we do not provide support for third-party products such as PowerShell nor SharePoint administration.

If you are concerned you might have any difficulty completing these steps, please consider a solution with our consulting team, contact us. This will ensure a fast, cost-effective, and stress-free implementation.

2. Prerequisites

2.1. How it works

The product uses the Google Drive APIs to read the source and a mix of Graph APIs and CSOM calls to push the data to the target.

Migration from G Suite requires to set up an OAuth authentication with appropriate permissions.

Some contents/settings from Google Shared Drives can’t be migrated in the current version:

  • “Commenter” permissions. There is no equivalence in Office 365.
  • External Shared links.

2.2. Mapping Table

In Google Drive, there are permissions and metadata (createdby, modifiedby, etc.) that contain email addresses. During the migration, these addresses must be converted into target accounts.

To achieve this, Cloudiway uses a mapping table to perform the conversion.

Important: the mapping table must be exhaustive, any missing email address will not be converted, and would end up with the loss of permissions and metadata.

Prepare your mapping table for users and groups/teams in CSV format, ready to upload later on.

2.3. Source Prerequisites

To perform the migration, you will need to create a G Suite migration account, give access to your Drive API (Google feeds). The migration account must have full permission to each source Shared Drives that you wish to migrate. It’s therefore important that you notice that any Shared Drives cannot be migrated unless this new user is granted full access on Shared Drives.

If you give sufficient permissions to the Cloudiway service account (Google feeds), the platform can add the permissions to the Shared Drives for you.

Read more: G Suite Connector Configuration.

2.4. Target Prerequisites

We recommend creating an Office 365 account dedicated to the migration, that can be deleted once the migration is completed.

  • The migration account needs an Office 365 Teams License.
  • It must be SharePoint administrator.
  • It must not be configured with multi-factored authentication (MFA) or SSO (ADFS).
  • Legacy Authentication must be turned on.

Cloudiway automatically creates the team or Sharepoint site, therefore they don’t have to exist prior to the migration. If they already exist, it will be used and data appended to it.

2.5. Azure Active Directory Application

Graph APIs calls are performed through an Azure Active Directory Application which is granted specific permissions.

You can either create an Azure Active Directory Application manually or let the platform create one for you.

Please consult our How To Create Azure Apps Registration page to create the Azure Active Directory Application and associated permissions.

3. Create Your Connectors

For Cloudiway to migrate your Shared Drives, it needs to be able to communicate with both your source and target domains. To do this, Cloudiway uses connectors. You will need to set up a connector for each source tenant and each target tenant. Please refer to this page to configure your connectors.

For large projects, it’s possible to create multiple connectors that will be used in parallel. Please contact Cloudiway consulting services if you need to set up such configuration.

4. Google Shared Drives Migration Settings

Note: to test the migration, you can use a Trial License, please consult this article to assign a Trial License.

4.1. Group List

To perform the migration, navigate to Sites > Group List

4.1.3. Option 3: Add a shared drive manually

You can manually add the details of a shared drive to your list on the Cloudiway platform. Due to the lengthy URLs, we recommend you only use this option if it’s impossible to run Get List.

  1. Go to your Google Drive and Develop the Shared Drives section. Search for your shared drive and open it.
  2. Take note of the URL of the shared drive and the ID:
  3. On the Cloudiway platform, go to the Group List of the Group Migration menu.
  4. Click on MANAGE then Create
  5. Fill in all details for the shared drive to be migrated
  6. Click on the OK button.

4.2. Specify Your Destination

The product gives you the flexibility to migrate to a large choice of targets and gives you the possibility to reorganize your data. You can migrate your Shared Drives:

  • To different team channels
  • To different channels within a team
  • To different SharePoint sites
  • To different libraries within a SharePoint site
  • To different folders within a SharePoint library

Migration to SharePoint Sites:

Google Team Drives to Office 365 Modern Site

You can upload a User or Group list via CSV (use IMPORT) or CREATE your entries manually.

A template of CSV file is available on the platform when you click on IMPORT.

FirstName;LastName;SourceEmail;TargetEmail;DisplayName;EntryType;

  • User example: test;user1;test@source.com;test@target.com;test user;0
  • Group example: ;;testgroupe@source.com;testgroup@target.com;testgroup;1

EntryType: enter 0 for user, 1 for group.

FirstName and LastName: Leave blank for group.

4.6. Pre-Processing

The pre-processing tool creates the site or team at the target if it doesn’t already exist.

What does the pre-processing tool do in detail?

At the target:

      • It creates the team and channels.
      • It creates the SharePoint sites and libraries.
      • It uses the graph APIs (Client ID and Client Secret) and gives the owner role to the migration account defined in the target connector.
      • It migrates membership and ownership.

To pre-process a team, in Group List, select it and click on MIGRATIONPre-Processing.

The group or team is now ready to be migrated.

4.7. Migration

Before starting the migration, you must run the pre-processing (see step above) of the shared drive.

To start the migration, in Group List, select it and click on MIGRATIONStart.

This will schedule the migration. The migration will start as soon as there is a free spot on the platform.
