Google Drive to Google Drive Migration Guide

Introduction

• This is the complete onboarding task flow for migrating folders and documents from Google Drive to Google Drive.
• Complete each step in the order listed. Links to corresponding Knowledge Base articles are provided.
• The Source and Destination must both be paid versions of Google Drive. Free Google Drive accounts are not supported.
• The Source and Destination absolutely require a Google administrative account.
• Items and folders in "Shared with Me" will not be migrated. Only items in "My Drive" will be migrated. To migrate "Shared with Me" items, they must be added to "My Drive".
• MigrationWiz now supports the capability to share migration projects across a Workgroup. Migration projects are no longer tied to individual accounts, they are tied to Workgroups. When Workgroup Administrators turn on the Project Sharing feature, all Agents besides those who are Inactive are able to view all migrations projects.  For more information, visit Project Sharing in MigrationWiz.

Prepare the Source Environment

1. Enable OAuthentication 2.0 within your Google admin portal to grant MigrationWiz access to G Suite. This step will require a Google admin account. For guidance, see Enable access to G Suite using OAuth 2.0.
   
   Notes:
• If you are migrating from multiple domains, repeat the steps for each domain.

 Important:

• OAuth administrative credentials will not function properly with G Suite for Business Legacy free accounts. If a G Suite tenant is a G Suite for Business Legacy free account, end user credentials must be used. Refer to KB005124 for more information on migrating with end user credentials.
• Make sure there are no spaces before or after the scope entry. This will cause the authorization to fail.

1. Enable API Access. Log in to Google Admin portal > Security > API Reference > checkmark the Enable API Access button.
   
   Note: This extra step is mandatory when migrating from Google Drive.
2. Export mailboxes to CSV file(s). From Google Admin portal > Click Users > Click ⁝ (3 vertical dots) > Download Users > Download All Users > Click OK > Save.

Prepare the Destination Environment

• Grant MigrationWiz OAuth2.0 access to authenticate to Google Drive. This step will require a Google admin account. For guidance, see Enable access to G Suite using OAuth 2.0.

• Add users to Google Drive. Instructions are located here. 

    

  MSPComplete Steps

  1. Create the customer. KB005421
  2. Create the Source and Destination endpoints. KB005427
  • For the Source endpoint:
    • Click Endpoints > Add Endpoint, then enter endpoint name. For endpoint type, select Google Drive.
    • Enter the Google admin account email address and domain name in the appropriate fields.
    • Both the source and destination domains will need to be listed in the endpoint for the migration to be able to connect properly.
  • For the Destination endpoint:
    • Click Endpoints > Add Endpoint > Enter endpoint name > For endpoint type, select Google Drive.
    • Enter the Google admin account email address and domain name in the appropriate fields.
    • Both the source and destination domains will need to be listed in the endpoint for the migration to be able to connect properly.

   

  MigrationWiz Steps

  1. Create the Document Migration project. KB005070
  • Create the Document Migration project > Select the customer > Select the Source endpoint (Source Google Drive) > Select the Destination endpoint (Destination Google Drive).
  2. Add the accounts (also referred to as "items") that will be migrated to the project.
     
     Note: If using the Bulk Add option, only the Source and Destination columns need to be filled in. You can use the CSV file that was created under Step 3 of the Prepare the Source Environment section of this guide. KB004842
  3. Set the Project Advanced Options. KB004834
  • InitializationTimeout=28800000 - This increases the initialization timeout window to eight hours. KB005099
  • FolderLimit=20000 - This increases the maximum number of folders for the migration to 20,000. Large companies might have more than 10,000 folders (the default) to migrate, so we recommend increasing the folder limit to 20,000. KB005557
  • DocumentBrowsingMode=Moderate For more information, see How does Google Drive to Microsoft OneDrive with Moderate Mode work?
  • If you want to keep migrated items in Google format add ShouldConvertToDestinationFormat=1 for more information see How are format conversions handled from Google Drive to Microsoft OneDrive? And vice versa? 
    
    Note: There are no spaces on either side of the "=" sign, and the entries are case-sensitive, so pay special attention to the capital letters in the commands detailed above.
  • Notifications > Send successful migration and notification to: > Source email address (if users are still using the acquired company's G Suite Gmail) or Destination email address (if users have already been migrated to the acquiring company's G Suite Gmail).
  • Customize notification email. Checkmark the Customize "successful migration" email box. Add your own customization text and company name to this email.
    
    Note: Notifications should only be set up before the final pass. If performing a single, Full pass, set this up now. If you are following a Pre-Stage migration strategy, only set this up prior to the final Full (Delta) pass.
  • Set the value for maximum licenses to consume per item, per pass. The default value is one license per user, which allows up to 10GB to be migrated per user. However, if a user has 28GB of data, the migration will pause at 10GB, and you will have to assign more licenses to the user. The recommended maximum number of licenses to consume per user for a document migration project is five (5) licenses per user, which allows up to 50GB of data to be migrated per user. The project will only consume the number of licenses for the amount of data migrated. If a user has 28GB of data, then only three out of the five licenses will be consumed, and two licenses will remain. KB004890
  • Set the Advanced Option to send a notification to end users after the migration pass completes.
  4. Run Verify Credentials. KB004511
  5. Run an assessment to calculate the number of licenses required for your migration. KB005237
  6. Purchase licenses. We recommend that you purchase the User Migration Bundle license for this migration scenario. User Migration Bundle licenses allow you to perform multiple migrations of User mailboxes, documents, and personal archives, plus Google coexistence configuration, and allows the use of DeploymentPro to perform post-migration Outlook email profile configuration. Refer to these articles for more information:
     • How do I purchase licenses?
     • Apply User Migration Bundle licenses to the Customer's Users
     • Which migration license should I choose?
  7. Notify users that a migration is occurring. Send email to all users telling them the time and date of the migration. During this time, they should not modify any documents in their Source Google Drive accounts, because any modifications will not be included in the migration.
  8. Perform the migration using one of the following strategies:
     • Select the users > From the top navigation, click the Start button > From the drop-down list, select Full Migration > Click the Start Migration button. KB004938
     • Steps for a Full Migration pass:
     • Pre-Stage pass: Select the users > Click the Start button from the top, and select Pre-Stage Migration > Under the Migration Scheduling section, from the drop-down list, select 90 days ago > Click Start Migration. KB004938
     • Full (Delta) pass: Select the users > Click the Start button from the top, select Full Migration > Click Start Migration. KB004938
     • Steps for a Pre-Stage Migration:
  • For small- to medium-sized migration projects that have less than 500 users, we recommend a Big Bang Migration strategy. This is a single, full-pass migration.
  • For large migration projects that have more than 500 users, we recommend a Pre-Stage Migration strategy. This is a multiple-pass migration.
  9. Click the pie chart icon in the MigrationWiz dashboard to receive an email containing all the project migration statistics. KB004626

   

  Post-Migration Steps

  1. To prevent users from inadvertently logging in and using their Google Drive accounts on the acquired company's G Suite platform, decommission the Google Drive user accounts, or change their passwords.
  2. Notify users once the migration has completed.
     
     Note: If you set the MigrationWiz Advanced Option for Notifications, they will receive an email upon migration completion.
