Cloud migration
Google Cloud migration service
We plan and carry out your migration to Google Cloud from AWS, Azure, VMware, or your own servers. Inventory, architecture, and cost analysis are completed before migration begins.

How is migration to Google Cloud done?
Migration is done in four stages. First, an inventory of servers, applications, and databases and their dependencies is gathered. Then the target architecture and cost are designed. Workloads are migrated in groups, first to a test environment and then to production. In the final stage, cost and performance are optimized. A rollback plan is kept ready for each group.
Our migration method
- 01
Discovery and inventory
Servers, applications, databases, and the connections between them are gathered through automated tools and interviews.
- 02
Business and cost analysis
For each workload, a decision to rehost, replatform, rewrite, or retire, along with a Google Cloud cost estimate.
- 03
Landing zone
Networking, identity, permissions, logging, and budget structure are set up before migration begins.
- 04
Pilot migration
A non-critical workload is migrated, measured, and used to refine the process.
- 05
Phased migration
The remaining workloads are migrated in groups, outside business hours, with a rollback plan.
- 06
Optimization and handover
Sizing, committed-use discounts, monitoring, and documentation. Followed by managed support.
Where and how we migrate from
| Source | Typical method | What to watch for |
|---|---|---|
| AWS | Virtual servers to Compute Engine, containers to GKE/Cloud Run, databases to Cloud SQL | Data egress cost and differences in the IAM model |
| Microsoft Azure | Virtual machines to Compute Engine, SQL databases to Cloud SQL | Entra ID identity integration and Windows licenses |
| VMware | To VMware Engine as-is, or converted to Compute Engine | License renewal date and network design |
| On-premises physical servers | Virtualized and migrated to Compute Engine | Hardware-dependent applications and license keys |
Google programs that reduce migration cost
Google offers credits and assessment support that cover part of the cost for eligible migration projects (for example, the Rapid Migration and Modernization Program). We check during discovery whether your project qualifies for these programs.
