Hi,

We recently completed a Microsoft 365 Tenant-to-Tenant (T2T) migration and had similar requirements (Exchange Online, OneDrive, SharePoint, and Teams data).

After evaluating a few options, we used CloudBik Microsoft 365 Migration Services, and the experience was smooth overall.

What worked well for us:

Secure Tenant-to-Tenant migration

Accurate permission and role mapping

SharePoint site and document library migration

OneDrive data transfer with folder structure intact

Minimal downtime during mailbox migration

Detailed migration reports

One of the key advantages was metadata preservation and version history handling, which is usually a challenge in large migrations.

If you’re planning a complex or enterprise-level migration, CloudBik is definitely worth evaluating.

Hope this helps!

Thanks for sharing the CloudBik experience. Sounds like it covered the key bases well, especially the metadata/version history handling, which is often the trickiest part of T2T migrations.
For anyone still comparing options, EdbMails Office 365 Tenant to Tenant Migration is also worth putting on the shortlist for enterprise-scale projects. A few things it handles well:

Direct mailbox, public folder, and archive mailbox migration between tenants, no PowerShell scripting required
Automatic target mailbox creation and license assignment
Incremental (delta) migration, so re-runs only move new/changed items and avoid duplicates
Concurrent mailbox migration to cut down migration windows on large mailbox counts
Detailed post-migration reports for verification

EdbMails also has separate tools for SharePoint, OneDrive, and Teams migration if you need the full Microsoft 365 footprint covered, not just mailboxes. There's a free trial available if you want to test it against your own tenant before committing to a license.
Worth a look alongside CloudBik for comparison.

We recently completed a Microsoft 365 tenant migration after our company acquired another business, and I wanted to hear how others handled similar projects. We initially considered PowerShell and native Microsoft methods, but managing mailbox mapping, permissions, and SharePoint structure looked far more complicated than expected.

During our research, we came across MacSonik Office 365 Tenant to Tenant Migration while comparing enterprise migration solutions. We eventually tested a Graph API-based migration tool that could transfer Exchange Online mailboxes, OneDrive accounts, and SharePoint sites without affecting the original data. The biggest advantage for us was that emails, contacts, calendars, attachments, permissions, metadata, and the original folder hierarchy stayed intact throughout the migration.

Another feature we appreciated was secure authentication. Since the migration involved confidential business information, we wanted a solution that didn't store credentials or mailbox content. The encrypted Microsoft 365 connection gave our IT team much more confidence than manual export/import methods.

We also migrated multiple users simultaneously, which saved an incredible amount of time. Instead of processing accounts individually, bulk migration handled hundreds of mailboxes in one operation. Detailed migration reports and activity logs also made it easy to verify everything after completion.

Has anyone else compared automated Graph API migration tools against Microsoft's native approach? I'd love to know whether your experience was similar, especially for mergers or tenant consolidation projects involving Exchange Online, OneDrive, and SharePoint.
