Cutover Exchange Online Migration from a Third-Party Hosted Exchange Server: 7-Days Consulting Service

This service facilitates migrating from an Exchange Server to Exchange Online, expanding your utilization of Microsoft 365. Migration is feasible using each user's credentials.

This migration occurs in the cutover migration mode when all information from mailboxes is immediately transferred to a new location.

During MX record switching, the email service may be unavailable. The downtime depends on the DNS settings of your provider and the DNS system features of email senders.

You can also use the additional email caching service, which will allow you to receive all emails regardless of the MX switching duration.

IT Partner responsibilities

• Hold a kickoff meeting to exchange contact information, plan key steps, and discuss the project
• Plan and guide the cutover from the source system to Exchange Online
• Provide new Exchange Online mailboxes by creating Microsoft 365 user accounts and assigning Exchange Online user licenses
• Add and validate email domain(s) to Microsoft 365
• Start a migration batch
• Provide a report with the number of mailboxes that were successfully migrated and those that cannot be migrated, if any
• Incremental mailbox synchronization setup to receive any emails sent after the start of the main synchronization
• Resolve any migration issues and errors to ensure that all mailboxes have been successfully migrated
• Change DNS settings and control their application
• Monitor health and status of the destination Exchange Online environment to make sure the migration process is correct

Client responsibilities
