Cloud Migration

Planned workload moves to cloud with cutover paths and risk controls.

Cloud migration programs that prioritize business continuity: inventory, dependency mapping, target design, pilot migrations, and controlled cutovers. We treat data movement, DNS, secrets, and rollback as first-class work—not an afterthought on migration day.

Who it’s for

  • Companies leaving a data center or legacy hoster
  • Teams consolidating workloads onto AWS, Azure, or GCP
  • Orgs migrating after an architecture decision is made

Problems we address

  • Dependencies between apps are poorly documented
  • Previous migration attempts caused extended downtime
  • Success criteria for cutover were never defined

Expected outcomes

  • Discovery and dependency mapping before move waves
  • Pilot migrations that prove the pattern
  • Cutover runbooks with rollback criteria

Process

A clear delivery path from discovery through handover and optional support.

  1. 01

    Discovery

    Goals, constraints, success criteria, and current-state review.

  2. 02

    Architecture

    Target design, interfaces, risks, and delivery sequence.

  3. 03

    Implementation

    Incremental build with visible progress and documented decisions.

  4. 04

    Testing

    Functional checks, failure paths, and acceptance criteria validation.

  5. 05

    Deployment

    Controlled release to staging and production with rollback paths.

  6. 06

    Handover

    Runbooks, access notes, and operator/admin walkthrough.

  7. 07

    Support

    Optional hypercare window or retainer continuity after go-live.

FAQ

We recommend per workload. Some systems should move with minimal change first; others benefit from containerization or managed services during the move.

Often yes using replication or staged cutovers. Achievable downtime depends on data size, change rate, and application tolerance.
