2. Gmail to Office 365 migration prerequisites

   Before you begin Gmail to Office 365 migration operation, it's important to make sure that your system meets the requirements for Office 365.

   • Step 1: Determine the number of users and create an Office 365 migration plan
     1. Before you begin the migration, determine how many user mailboxes you plan to migrate to Office 365. Based on this requirement, you can purchase a suitable Office 365 plan for your organization.
     2. Create a plan and schedule for the migration such as migration start and end date, the number of users being migrated, and the specific data that will be migrated.
   • Step 2: Enable two-step verification and create app password in Gmail
     1. Ensure to enable IMAP for Gmail / Gsuite accounts.
     2. To connect Office 365 with Gmail, you must enable two-step verification and also create an app password for your account.
   • Step 3: Evaluate the bandwidth and network requirements

     When you migrate from Gmail to Office 365, it's important to take into account the bandwidth and network requirements of the migration operation. The amount of bandwidth and network resources required depends on the number of mailboxes being migrated, the size of the mailboxes, and the migration method being used.

     • Connectivity: It's important to ensure that you have a stable connection to migrate all your emails between Gmail and Office 365. See networking roadmap for Office 365 which details the steps to plan and deploy your network for the migration.
     • Internet bandwidth: The migration requires a reliable and fast internet connection to transfer the data from Google Workspace to Office 365. See bandwidth requirements for Office 365 migration and also consider the Gmail bandwidth limits at the source.
     • Network latency: The network latency should be as low as possible. A latency of less than 150 ms is recommended. See how Microsoft 365 networking is different from IMAP servers.
     • Firewall configuration: Make sure that your firewall is configured to allow traffic to and from Office 365 which includes ports that are used for Exchange and Azure AD Connect. See the list of worldwide endpoints for Office 365.
     • Testing your network connection: With tools like Microsoft Remote Connectivity Analyzer and Microsoft 365 network connectivity test tool, you can test your existing network.

      See best practices for network planning and improving migration performance.

     Note: If you have already configured your Office 365 tenant, you can directly skip to Step 7 in this section.

   • Step 4: Choose a Microsoft 365 license option that suits your requirements

     Microsoft 365 is available as a cloud-based subscription service or as a one-time purchase of a perpetual license. Office 365 has different licensing plans each suited to different user requirements.

     It is recommended to thoroughly evaluate the Office 365 business plans and Office 365 enterprise plans to determine which one aligns with your organization's requirements. Alternatively, you can also sign up for a 30-day free trial of Office 365 and test the various plans before making a final decision.

   • Step 5: Set up your target Office 365 tenant for the migration

     Setting up the target Office 365 for the migration involves creating the tenant and configuring it to receive the migrated data from Gmail.

     • Create an Office 365 tenant: Plan for the tenant creation and deployment. See the tenant roadmap for Office 365.
     • Sign in to the Microsoft 365 admin center: Go to the Microsoft 365 admin center (https://admin.microsoft.com/) and sign in with your global administrator credentials.
     • Customize the tenant settings: After the tenant is set up, you can configure and customize the settings such as email domains, language, and time zone to suit your organization's needs.
     • Configure email clients and apps: If you want to install Office 365 apps and Outlook, see system requirements for Microsoft 365 and Office configuration support matrix. Because Office 365 is a cloud based solution, it is also important to learn where your Microsoft 365 customer data is stored.
     • Set up Office 365 services: Besides email, you may want to set up additional services such as SharePoint, OneDrive, Teams and OneNote.
     • Establish data retention policies: With Office 365, you have the ability to retain data in accordance with compliance and legal requirements. Set up data retention policies to meet your organization's compliance needs, and if necessary configure retention policies for specific mailboxes or groups of users
   • Step 6: Add and verify the custom domain on Office 365

     If you have a custom email domain from your hosting provider (such as GoDaddy, Cloudflare, AWS) to which you want to migrate and receive emails, you must add and verify the domain on Office 365. This will enable you to use your own domain name (such as example.com) for your email addresses and other Office 365 services.

      To set up your custom domain, follow these steps:

     • Verify that you own the domain by adding a TXT record to your DNS configuration. If you have your domain registered with GoDaddy, follow the instructions to connect your DNS records at GoDaddy to Microsoft 365.
     • Add a new domain to your Office 365 tenant. You can use an existing domain that you own or purchase a new one. The domain is used to access your Office 365 services.
     • Update your DNS records to point to Office 365. This step is required to ensure that your email is delivered to the correct mailbox. You can also perform this step at the end after the migration is complete.
   • Step 7: Create mailboxes and mail-enabled Public folders

     Before you migrate to Office 365, ensure that you create mailboxes for users in your organization and assign suitable licenses to them.

     • Add users and assign licenses to Office 365 users
     • Add several users at the same time to Office 365
     • Assign Microsoft 365 licenses to user accounts

       If you want to migrate your Google emails to Office 365 Public folder, ensure that you create and configure Public folders and make them mail enabled on Office 365.

     • Create Office 365 Public folder and assign mailbox user
     • Enable In-Place Archive mailboxes in Office 365
