Mergers & Acquisitions
Two companies merge — one Microsoft 365 tenant must move into the other. All Teams, channels, users, and files transfer to the acquiring company's tenant.

MIGRATION TRIGGERSS
Why organisations need Microsoft 365 tenant to tenant migration
Any time your organisation's Microsoft 365 environment needs to move to a new Azure Active Directory — whether from M&A, consolidation, or restructuring — a tenant migration is required.
Company Spin-offs
A business unit is sold or separated. Its Microsoft 365 data — Teams, SharePoint, OneDrive — needs to move to a new independent tenant.
Tenant Consolidation
Multiple Microsoft 365 tenants from regional or historical growth need to merge into a single unified tenant for centralised management.
Rebranding
Company rebrand requires a new domain and tenant — all existing collaboration history must carry forward without data loss.
Regional Restructuring
Data residency requirements or regulatory changes require moving users from one regional Microsoft 365 tenant to another.
GCC Migration
US government or defence organisations migrating between GCC, GCC High, and standard commercial Microsoft 365 environments.
Full scope coverage
Everything your Microsoft 365 users depend on — migrated with full fidelity
ZuniPixel migrates all eight categories of Microsoft 365 collaboration data — including what Microsoft's native Orchestrator doesn't cover.
| Workload | Microsoft native tool | ZuniPixel |
|---|---|---|
| OneDrive personal content | ✅ Supported natively | ✅ Included |
| Teams chats (1:1 and group) | ⚠️ Preview — limited fidelity | ✅ Full fidelity |
| Teams channels and history | ❌ Not supported | ✅ Full channel history |
| SharePoint sites | ❌ Not supported | ✅ With permission mapping |
| Meeting recordings | ❌ Not supported | ✅ Full Inventory and migration |
| Planner tasks | ❌ Out of scope | ✅ Plans, buckets, assignments |
| Guest and external access | ⚠️ Limited | ✅ Full guest mapping |

Five-phase process
How ZuniPixel runs your Microsoft 365 tenant to tenant migration
The same five-gate process your programme office expects — with evidence in and evidence out at every stage.
Scan
Connect
Map
Migrate + Delta
Validate
Scan
Pre-migration inventory of source M365 tenant — users, teams, channels, DM pairs, SharePoint sites, recordings, files, and timing estimates.
Connect
OAuth 2.0 into source and destination tenants. Least-privilege Microsoft Graph API roles with auditable permission scopes.
Map
Identity mapping, team structure mapping, guest mapping, and entitlement mapping. CSV-driven bulk layout for enterprise scale.
Migrate + Delta
Parallel throughput with continuous delta passes. Users stay productive on source until cutover is declared by your IT team.
Validate
Signed completion reports covering scope, delta coverage, remediation queue, and go-live readiness for programme closure.

Where native tools fall short
What Microsoft's Cross-Tenant Migration Orchestrator doesn't cover
Microsoft's Orchestrator (released December 2025, still in preview) simplifies mailbox, OneDrive, and Teams chat migration. But it has explicit scope limits that affect most enterprise projects.

Security & trust
Designed for enterprise Microsoft 365 security and compliance reviews
Your CISO and security team will ask specific questions. Here are the architecture specifics — not marketing adjectives.
Graph-native transport
ZuniPixel orchestrates Microsoft Graph routes your tenant already trusts — no shadow middleware copying message bodies outside Microsoft's infrastructure.
Encryption throughout
TLS 1.2+ for every call, AES-256 payload protection, configurable data retention aligned to your policy. Nothing stored after job completion.
Least-privilege operations
Scoped app permissions, just-in-time elevation patterns, and exportable audit log for every job action — ready for your security team's review.

Common questions
Microsoft 365 tenant to tenant migration — answered
Migration duration depends on tenant size — total users, message volume, and file storage. Most mid-market migrations (5,000–20,000 users) complete their first pass within a standard business day. Larger enterprise tenants (50,000+ users) typically run overnight. ZuniPixel's pre-migration scan produces a specific time estimate for your tenant before committing to a cutover window.
ZuniPixel migrates both. Teams chats (1:1 and group DMs) are migrated with full message history and attribution. Teams channels — including public channels, private channels, channel message threads, replies, files, tabs, and Planner — are migrated with complete structural fidelity. This is a key difference from Microsoft's native Cross-Tenant Migration Orchestrator, which handles Teams chats but does not migrate Teams channels or channel history.
Yes — and this is a common approach for large enterprise migrations. Microsoft's Orchestrator handles mailboxes and OneDrive personal content. ZuniPixel handles Teams channels, SharePoint sites, meeting recordings, and Planner — the workloads the Orchestrator doesn't cover. ZuniPixel's scope controls let your IT team configure exactly which workloads to include so there's no duplication or conflict between the two tools.
This is exactly what delta migration handles. Users continue working on the source tenant during the first migration pass. All new messages, files, and changes created during that window are captured and synced in the delta pass before go-live. Nothing is lost in the gap. ZuniPixel includes full delta migration as standard — not as an add-on.
Yes. ZuniPixel gives you full control over migration scope. You can select specific teams, individual channels, or defined user groups rather than migrating the entire tenant. This is particularly useful for phased M&A rollouts — for example, migrating one business unit at a time — or for selective divestitures where only a subset of data needs to move to the new tenant.
Teams to Teams migration typically refers to moving Teams-specific data between tenants. Microsoft 365 tenant to tenant migration is the broader term covering the full scope: mailboxes, OneDrive, SharePoint, Teams, and all associated identities and permissions. ZuniPixel covers the full Microsoft 365 scope, not just Teams. Most enterprise migrations require the complete tenant migration approach rather than a Teams-only migration.
Cross-region migrations — from a US Microsoft 365 tenant to an EU tenant, or between standard commercial and GCC environments — are supported. Regional data residency rules are handled during migration scope configuration. We recommend raising your specific region combination during the pre-migration consultation so our team can confirm compatibility and flag any Microsoft-imposed constraints.
All data is encrypted in transit using TLS 1.2+ and AES-256. ZuniPixel connects to Microsoft 365 exclusively via the official Microsoft Graph API — no third-party data routing, no intermediate storage of message content beyond the active migration job. A complete audit log of every migration operation is generated and available for export post-migration.
