Migrations
We consolidate and move content and identities from on-premises systems and other clouds into Microsoft 365 or Google Workspace.
Overview
We plan and run migrations from on-premises to cloud and between clouds with minimal downtime and verified data integrity.
- DiscoveryDependency mapping and grouping into migration waves.
- ReplicationData replicated to the target while the source stays live.
- CutoverShort switch of users, identity and DNS, with rollback plans.
- ValidationPerformance, cost, security and integrity checks before the old system is retired.
Technical scope
- Discovery and dependency mapping
- Server, virtual machine and database migration
- Mailbox, file and application migration
- Network, identity and DNS cutover
- Cloud-to-cloud moves between AWS, Azure and Google Cloud
- Performance, cost and security validation
- Rollback plans and hybrid coexistence
Architecture and how it works
Source systems are discovered and grouped into waves. Data is replicated to the target while the source stays live. A short cutover switches users and DNS, and validation confirms integrity before the old system is retired.

Tools and deliverables
Migration plans record the inventory, dependency map, wave schedule, cutover steps and rollback criteria. Validation reports compare source and target for data integrity, performance and security settings before the old system is retired.

Common questions
How are workloads grouped for migration?
Discovery and dependency mapping show which systems talk to each other, and which applications, databases and services rely on them. Workloads are then grouped into waves so that dependent services move together, which avoids breaking connections between systems that were moved at different times.
How is data replicated without long downtime?
Data replicates to the target while the source stays live, so users keep working. A short cutover then switches users and DNS, which limits the outage to the final synchronisation and the switch itself, and a rollback plan is kept ready in case the new environment does not behave as expected.
How do you handle identity, DNS and mail?
Network, identity and DNS cutover are planned explicitly rather than left to the end, and mailbox migration can use Exchange hybrid so that users and mail flow coexist during the move. This lets mailboxes move in batches without a disruptive single-day change or a break in mail delivery.
How is the migration validated?
We check data integrity, performance, cost and security settings on the target before retiring the old system, and keep a rollback plan until sign-off. Validation results are recorded, so the business can confirm that nothing was lost or weakened in the move before the source environment is switched off.
