Microsoft 365 (M365) tool vendor ShareGate has announced support for tenant-to-tenant mailbox migrations.
According to Haziqa Sajid, writing on the ShareGate website, tenant-to-tenant mailbox migration capabilities were some of the most requested features from users, with mailboxes also representing the “number-one migration workload for M365 after SharePoint”.
“This new functionality now makes ShareGate the complete migration package, set to allow our users to seamlessly migrate to M365 with zero hiccups holding anyone back,” Sajid claimed.
IT professionals would be able to do more with less, while managing M365 proactively, according to ShareGate. Mailbox migrations are now available in public preview, with full rollout expected over the coming months, she said.
With the public preview release, ShareGate supports tenant-to-tenant mailbox migration from Exchange Online to Exchange Online or M365. Tenant-to-tenant mailbox migration can contribute to migration problems and delays, especially in large, complex M365 environments, Sajid noted.
“Migration needs to just work without becoming its own thing,” she said. “A common migration scenario: users use Microsoft native tools like the cross-tenant mailbox migration tool, and realise they’re not particularly easy to use.”
Sajid said that Microsoft’s own migration offering for tenant-to-tenant migrations was a paid add-on to boot. At the same time, different tools could make things take longer and add complexity.
“Most solutions on the market, including Microsoft native tools, are clunky and difficult to learn,” she said. “This often leads to spending more time to ensure everything has been moved correctly rather than simply executing the migration.”
ShareGate sought instead to simplify migrations, with new benefits including the ability to copy selections for all mailboxes or custom groupings, “intact” migration of messages, attachments, and folders, configurable mapping, attribute labelling for messages, plus reporting and controls such as phased migration features to automate transfers over a given period of time, Sajid noted.
“With date-frames that enable you to bring over only what you need with filters that will copy three or six months of messages or set your custom time-frame,” she said.
The ShareGate migration tool is a client-side only application that uses application programming interfaces (APIs) and other methods to copy source elements at the destination.
For instance, to migrate from Google Drive, the ShareGate migration tool sends requests to the Google APIs to authenticate the account and get the data. Google drive content, permissions, and metadata can then be packaged and sent to the ShareGate migration tool, according to ShareGate.
