Cost of migrating office 365 mailboxes to a new tenant

The cost of migrating Office 365 mailboxes to a new tenant can vary depending on several factors, such as the number of mailboxes, the complexity of the migration, and the services required. Here are some general estimates:

Migration Methods:

  1. Manual Migration: This method involves manually moving mailboxes from the old tenant to the new tenant using PowerShell or the Office 365 admin center. This method is free, but it can be time-consuming and requires technical expertise.
  2. Automated Migration: This method uses third-party tools or Microsoft's built-in migration tools, such as the Office 365 Migration Tool or the Azure AD Connect tool. These tools can automate the migration process, but may require a license fee or a subscription.

Cost Estimates:

  1. Manual Migration:
    • Time: 1-5 days, depending on the number of mailboxes (estimated 1-2 hours per 100 mailboxes)
    • Labor cost: $500-$2,000, depending on the hourly rate of the IT professional
  2. Automated Migration:
    • Tool license fee: $500-$5,000, depending on the tool and the number of mailboxes
    • Professional services: $1,000-$5,000, depending on the complexity of the migration and the hourly rate of the IT professional
  3. Microsoft's Migration Tool:
    • Free, but may require a Microsoft 365 subscription or a one-time payment

Additional Costs:

  1. Domain Name System (DNS) Changes: If you need to update your DNS settings to point to the new tenant, you may need to pay a DNS provider for the changes.
  2. Email Address Changes: If you need to update email addresses or create new email addresses for users, you may need to pay for additional email addresses or domain names.
  3. User Training: If you need to provide training to users on the new tenant, you may need to pay for training services or materials.

Total Cost:

The total cost of migrating Office 365 mailboxes to a new tenant can range from $1,000 to $10,000 or more, depending on the complexity of the migration, the number of mailboxes, and the services required.
