Earthlink email to Office 365 Migration

1. EarthLink email to Office 365 migration plan

   Planning is one of the most important steps before you begin the EarthLink email to Office 365 migration. Here is a checklist of points to consider before you migrate.

   1. Stakeholder Communication & Change Management: Before migration, communicate with all users about the plan, timeline, and expected changes. Provide training sessions or guides on using Outlook and Microsoft 365 tools to ensure a smooth transition and reduce user confusion after migration.
   2. Migration Scheduling (“Who Should Migrate When”): Start with a pilot migration, move a small department or a few users first to test the process and identify any issues. Once the pilot succeeds, proceed to migrate larger groups in phases for better control and minimal disruption.
   3. Licensing Considerations: Compare EarthLink and Office 365 plans to understand the cost differences and feature upgrades. Choose appropriate Microsoft 365 licenses based on each user’s needs such as storage, desktop apps, and collaboration tools.
   4. Compliance, Retention & Governance: Highlight how Office 365 enhances data management with features like Data Loss Prevention (DLP) and retention policies. These help meet business compliance standards, secure sensitive data, and maintain legal data retention requirements.
   5. Ensure Sufficient Network Capacity and Bandwidth: Before starting the migration, verify that your internet connection can handle large data transfers without interruptions. Adequate network speed and bandwidth ensure faster mailbox uploads, prevent timeouts, and minimize migration delays.

       • Click ‘IMAP Migration CSV File’. It will load the sample CSV file to your local drive.

         

       • Open the CSV file and fill in the necessary details, including the email address, password, IMAP server hostname, and port number for each mailbox. After completing the entries, save the file to proceed with the migration.

         

       • Once you've made the necessary changes to the CSV file, save and close it.
