QuChuhai delivers AWS migration services for internet, gaming, and AI application companies. From assessment and incremental data sync to rehearsed cutover and rollback safeguards, we use a proven, reversible migration playbook so your business keeps running while you move to AWS, migrate accounts, or expand regions.
We do one thing: migration. We fold the complexity of cross-account, cross-region moves into a repeatable, reversible process.
Move TB-scale object storage between accounts and regions — data, permissions and encryption together.
binlog-based incremental replication brings cutover downtime down to minutes — or less.
Move instances, images and network topology to the target account / region, with IAM and security groups sorted.
Account merges, splits and org clean-up — tidy up multi-region architecture as you go global.
Understand before you move: inventory, dependency mapping, downtime windows and risk assessment.
On-call through the cutover window, with monitoring and stabilization support after go-live.
A migration process distilled into a playbook that keeps TB-scale S3 and database migrations inside a controlled downtime window.
Inventory assets, dependencies and data volume; estimate downtime.
Target architecture, migration path, cutover & rollback plan.
Target environment, network / IAM, replication pipeline.
Full + incremental sync with data-consistency validation.
Rehearse once, then cut over in a minimal window.
Post-launch monitoring, alerting and stabilization.
We don't "stop the world and copy data." Incremental replication plus a rehearsed cutover keep your business online throughout.
Full load first, then continuous CDC / binlog sync. At cutover we only reconcile the last delta — not migrate a whole database under downtime.
Before cutover we reconcile row counts, checksums and key business metrics. We only cut over once both sides match — no "wrong data after the switch."
We run a full cutover rehearsal in a staging environment and write it up as a runbook. The real cutover follows the script, so timing is predictable.
Every step keeps a rollback path. If a cutover goes wrong, we roll back to the source environment quickly — no data loss, no business impact.
Move single-region or on-prem workloads to an AWS overseas region to support a new market, balancing latency and compliance.
Migrate production resources and data between AWS accounts for reorganisation, M&A or compliance.
When switching cloud reseller or operating entity, move production data and services from the old account to the new one.
Stand up disaster recovery or a multi-active setup in another region, reusing the same replication and validation pipeline.
Not generic "cloud consulting." The pitfalls of cross-account, cross-region moves are distilled into a reusable playbook.
Our process and tooling align with official AWS migration and account-governance guidance — auditable, reversible at every step.
Our customers are internet, gaming and AI teams expanding overseas. We know the real cross-region, cross-account pitfalls.
Most migrations use incremental replication plus a rehearsed cutover: data is continuously synced and caught up beforehand, so the actual cutover only needs a short window to reconcile and switch traffic — typically under 30 minutes, and minute-level in some cases. The exact window is estimated during assessment.
We never cut over without validation. Before cutover we reconcile row counts, checksums (S3 ETag / checksum, database consistency comparisons) and key business metrics; we only switch once both sides match, and re-check by sampling afterwards.
Yes. Every step in the plan has a rollback path, and the source environment stays writable or quickly recoverable during cutover. If anything looks wrong, we roll back to the source per the runbook with no business impact.
It depends on data volume, dependency complexity and cutover requirements. Assessment (1–2 weeks) produces a clear timeline; data sync runs continuously in the background without consuming your downtime window — real downtime happens only during the final cutover.

The whole migration runs on native AWS capabilities: cross-account access via least-privilege IAM roles, encryption in transit and at rest (KMS) preserved, and permissions / policies migrated with the data. We don't retain your business data; access is granted on demand and revoked after use.
