A Microsoft 365 tenant merger should start with an inventory and a clear plan. Identify source tenants and list workloads to move, including Exchange Online mailboxes, OneDrive accounts, SharePoint sites, and Teams data. Record users, ownership, permissions, file locations, and dependencies. Decide what should move & what can remain. Prepare the destination tenant by creating required accounts, assigning licences, confirming administrator access, and checking storage. A workload-by-workload plan helps define responsibilities and avoid rushed transfers.
For the transfer, Aryson Tenant-to-Tenant Migration Tool supports moving selected Microsoft 365 workloads between tenants. Administrators can connect both tenants, choose mailboxes, OneDrive accounts, SharePoint sites, or Teams data, and select required users or content. Bulk migration and user mapping help manage multiple accounts and match source users with destination accounts. Mailbox migration supports emails, attachments, contacts, calendars, tasks, permissions, rules, and automatic replies. The software also supports OneDrive files and folders, SharePoint sites and document libraries, and Teams collaboration content. Review selections and mappings before starting.
During a Microsoft 365 tenant merger, plan for duplicate content, staged transfers, and post-migration checks. The software includes email, OneDrive, and SharePoint deduplication, plus an option to skip previously migrated data. Date-range and file filters help narrow the migration scope. Supported options retain mailbox folder hierarchy, file and site structure, and metadata. Version history and other options depend on the workload and selected settings. For Teams, review the teams, channels, messages, files, and other supported collaboration items chosen for transfer. Keep records of workloads, mappings, filters, and exceptions.
After each job, review migration reports and activity logs. Verify destination mailboxes, OneDrive folders, SharePoint libraries, and Teams content with relevant owners. Check user access and permissions, then investigate failed or skipped items. Communicate planned changes and obtain business-owner sign-off. Content migration does not automatically move every tenant-wide setting, identity configuration, domain, device, licence, or compliance policy. Assess these separately and configure them where required. A phased rollout, clear responsibilities, and documented checks help keep the project organised stepwise.
