Tenant migration
A specialist migration track for mergers, acquisitions and carve-outs where two Microsoft 365 tenants need to be consolidated or separated.
Cloud migration
From on-premises to Microsoft Cloud — securely and in control
Migrating to Microsoft Cloud is not just a technical task. It requires clear architecture, thorough planning and a partner who knows the difference between theory and practice. From classic on-premises-to-cloud migrations to complex tenant-to-tenant consolidations during mergers and acquisitions — inciro makes sure the move happens correctly, first time.
The challenge
What typically goes wrong in migrations
Underestimated complexity
Many migrations start as a technical exercise and end as architectural and organisational chaos because dependencies were not mapped from the beginning.
Insufficient planning
Without a clear prioritisation of workloads and a realistic timeline, the project drifts. Budgets are exceeded and the outcome falls short of expectations.
Security and compliance overlooked
In the rush to move to cloud, controls, policies and access management are skipped. Fixing them afterwards is far more expensive than building them in correctly from the start.
What we do
Migration with senior architecture throughout
inciro handles migration end to end — from the initial mapping of your existing environment to the final handover to operations. We combine experienced architects who design the solution with specialists who implement it.
We work pragmatically. That means we do not try to move everything at once if it does not make sense. We prioritise the workloads that deliver most value early and make sure the foundation is built correctly before the rest follows.
In migration projects, communication is often just as critical as the technical work itself. Different teams, suppliers and management layers do not see the same details, and in global organisations that only becomes more complex. Here we use AI internally to make technical plans, dependencies and decisions easier to understand across roles and languages. That improves alignment and reduces misunderstandings, without handing architecture ownership or cutover responsibility to machines.
Our approach means you do not need to coordinate three separate suppliers. inciro takes responsibility for architecture, implementation, security and communication — and you have one consistent point of contact who understands the full picture.
Tenant-to-tenant migration is a scenario we particularly enjoy working on. It typically arises during mergers, acquisitions or divestments, where two Microsoft tenants need to be consolidated or separated. Exchange Online, Teams, SharePoint, Entra ID and Azure resources across two separate tenants require a carefully coordinated approach, clear cutover plans and a partner who has been through it many times before. We have.
Migration phases
A structured path to Microsoft Cloud
Discovery and assessment
We review your existing infrastructure, workloads, dependencies and compliance requirements to build a complete picture.
Architecture and plan
We design the target architecture in Microsoft Cloud and produce a detailed migration plan with workload prioritisation and risk assessment.
Pilot migration and testing
We run a controlled pilot migration, validate assumptions and adjust the plan before full migration begins.
Full migration and handover to operations
We complete the remaining migration, ensure stable operations and document the new environment so you are self-sufficient afterwards.
Who this is for
For organisations that want to migrate correctly
Cloud migration with inciro is suited to organisations that want to move to Microsoft Cloud — or consolidate and modernise an existing cloud environment — with a focus on security, stability and long-term operations.
- Organisations with on-premises infrastructure that needs modernising
- Organisations migrating from a competing cloud platform to Microsoft
- Organisations going through a merger, acquisition or divestment that need to consolidate or separate Microsoft tenants
- Companies with an existing Azure environment that has grown without governance
- IT teams lacking architectural capacity to plan and manage the migration
- Organisations with compliance requirements around security, identity and data residency

Questions and answers
What you might want to know
How long does a typical migration take?
It depends heavily on scope, complexity and the organisation's readiness. A focused migration of specific workloads can be completed in a few months. A full infrastructure migration for a larger organisation typically takes 6 to 18 months. We provide a realistic estimate after the initial assessment.
Can we keep running during the migration?
Yes. We always plan the migration to minimise operational disruption. This typically involves running environments in parallel for a period, test phases and a controlled cutover — adapted to your specific situation and the criticality of your systems.
What about our existing Microsoft licences?
We review your licensing situation as part of the assessment phase. In many cases there are opportunities to optimise licensing during the migration, so you are not paying for more than the new environment requires.
Does inciro handle security and compliance as part of the migration?
Yes. Security and compliance are integrated into our migration approach — not a separate layer added afterwards. We design access management, network security and compliance controls into the solution from the start.
What happens once the migration is complete?
We close with documentation and handover to your operations team. From there you can engage us for ongoing review and optimisation, or manage the environment independently. We do not tie clients into ongoing contracts.
Can inciro help with tenant-to-tenant migration for a merger or acquisition?
Yes — and it is one of the scenarios we most enjoy working on. Tenant-to-tenant migration is technically complex and organisationally demanding. It involves far more than moving data: mail flow, Teams channels, SharePoint sites, calendars, access management and Azure resources all need to be handled in a coordinated way across two separate tenants. We plan and execute the full engagement — from mapping both tenants and designing the migration strategy through to final decommission — making sure users and leadership always know what is happening and when.
