Microsoft has introduced a long-awaited tenant-to-tenant migration feature in Microsoft 365. This allows organizations to transfer Exchange Online mailboxes, OneDrive data, Teams chats, and meetings directly between different tenants. Given this update, I'm really curious about how effective the migration is in real-world scenarios—especially regarding coexistence, staged migrations, and post-move cleanup. Has anyone started testing this feature, or are there plans to use it during a merger or acquisition?

It seems like a game-changer, but remember, migrating might still be tricky. I've had a rough experience using Microsoft's earlier tools; they can be buggy. I think for peace of mind, tools like BitTitan still offer reliability, especially if you face any hiccups during migration.
Just a heads up, while this feature will ease moving user data, it's not a silver bullet. You'll need licenses for every user, and it's crucial to plan properly. There are still many elements like SharePoint sites, Teams apps, and mailbox permissions that need separate attention. If you're dealing with larger migrations, don't forget about device management and domain detachments—those are often major headaches.
This feature is highlighting divestiture scenarios, so if you’re looking to export a domain from your existing tenant to a new one, it seems like it would support that. However, make sure you plan it out as conditions can vary.
Alright, so what about using this tool to migrate from a GoDaddy-hosted tenant to a standard Microsoft tenant? The good news is, detaching from GoDaddy is easy—you can either do that yourself or reach out to their support. But make sure that’s sorted before your migration.
The new migration feature is part of the Migration Orchestrator, which includes a set of PowerShell modules and a beta Graph API. However, it’s quite limited; it primarily focuses on user content. You’ll need to handle the creation and identity matching yourself, and don’t expect to migrate shared content like Teams or SharePoint sites without additional tools. This tooling primarily fills a gap for smaller migrations, which is a relief for many who want to avoid third-party services like BitTitan or Quest.
