FAQ

M365 Archive Migration FAQ

Everything you need to know about archive migration

What is Microsoft 365 Online Archive Migration?

Microsoft 365 Online Archive Migration is the process of migrating the content stored in Microsoft 365 Online Archive mailboxes to a different destination - either another Microsoft 365 tenant (mailbox, archive, or shared mailbox) or Google Workspace.

Where can I migrate Online Archives to?

You can migrate Online Archive content to Microsoft 365 primary mailboxes, Online Archives, shared mailboxes, or to Google Workspace (Gmail). The destination can be configured per user or globally.

What data is preserved during migration?

Cloudiway preserves all email metadata including sender, recipients, dates, categories, flags, read status, and folder structure. Attachments, embedded images, and message properties are fully maintained.

How long does an Online Archive migration take?

Migration duration depends on data volume. With concurrent migrations and delta passes, most projects complete within days. Pre-staging allows gradual data transfer with minimal cutover downtime.

Is there data loss risk during migration?

No, Cloudiway uses delta synchronization to ensure complete data transfer. Multiple passes capture any changes made during migration, and detailed reports verify successful transfer of all items.

Can I filter what gets migrated?

Yes, advanced filtering allows you to migrate based on date ranges, specific folders, message size, and other criteria. This is useful for compliance requirements or selective migration.

Does this support Office 365 archive migration?

Yes. Office 365 was rebranded to Microsoft 365 in 2020, but the archive migration process is the same. Cloudiway migrates email archives to Microsoft 365/Office 365 in-place archives and online archives seamlessly.

Do users keep accessing their Online Archive during the migration?

Yes. The migration runs server-side via the Microsoft Graph API, so end users continue to read, search and file mail from their Online Archive throughout the project. New items received during migration are picked up by the next delta pass, and the cutover window is limited to the final synchronization rather than to the entire data move.
