Migrate VMs, storage, and networking from one provider to another — with zero-drama cutover, rollback, and post-migration optimization.
Talk to a migration engineerInfrastructure migration is risky. A botched cutover means downtime, data loss, and angry customers. Most migrations fail not because of the technology but because of poor planning — incomplete dependency mapping, untested rollback, no cutover runbook, and no post-migration monitoring. The result is a 2am fire drill that nobody enjoys.
CB4UHost migrates infrastructure the boring way: detailed planning, dry-run rehearsals, tested rollback, and post-migration monitoring. We've migrated VMs, storage, and networking across AWS, GCP, Azure, OVHcloud, Hetzner, on-prem, and back. We know the gotchas — and we plan around them.
We're vendor-neutral on both ends. We'll migrate you from AWS to GCP, from on-prem to cloud, from cloud to dedicated, or from one VPS provider to another. The right destination depends on your workload — we'll recommend if you haven't decided.
Every migration ends with a post-mortem, optimization recommendations, and a 30-day monitoring window to catch any issues that surface after cutover.
Complete map of VM-to-VM, VM-to-storage, and VM-to-network dependencies — no surprises during cutover.
Step-by-step cutover runbook with timestamps, owners, and rollback triggers.
We rehearse the cutover in a staging environment to catch issues before the real thing.
We execute the cutover (often over a weekend) with on-call support and tested rollback.
30-day monitoring window to catch latency, error rate, or cost anomalies.
Right-sizing, reserved capacity, and architecture recommendations for the new environment.
We inventory your infrastructure and map all dependencies.
We build the cutover plan, rehearse it in staging, and refine.
We execute the cutover with on-call support and tested rollback.
We monitor for 30 days and fix any issues that surface.
We right-size the new environment and make architecture recommendations.

For VM migrations with proper planning: 0-30 minutes of downtime during cutover. For storage-heavy migrations: 1-4 hours. We'll give you a specific estimate after discovery.
We test rollback before cutover and have a rollback runbook ready. If anything goes wrong, we roll back to the original state within the agreed rollback window (typically 30-60 minutes).
Sometimes — it depends on the workload. Stateful databases can be migrated with replication + cutover (seconds of downtime). Stateless web tiers can be migrated with blue-green deployment (zero downtime). We'll tell you what's possible after discovery.
Yes, if you haven't decided. We'll recommend based on your workload — see our Hosting Comparison and TCO Analysis services.
Move applications between clouds, providers, or architectures — with refactoring options from lift-and-shift to full replatforming.
Migrate databases, data warehouses, and data lakes with replication, validation, and zero-data-loss cutover — across providers and formats.
We evaluate your workloads, data, security posture, and team readiness to determine which apps should move to cloud — and which should stay.
