Server Migration

Host and VM moves between machines, hypervisors, or hosting providers.

Server migration for VM-to-VM, host refreshes, and provider changes when a full cloud re-architecture is not the point. We plan disk and data copies, cut services over cleanly, and verify application health after the move.

Who it’s for

  • IT teams refreshing aging hosts or hypervisors
  • Companies changing hosting providers
  • Ops groups consolidating underutilized servers

Problems we address

  • Servers must move but application owners fear downtime
  • Disk and configuration differences break services after copy
  • No verified rollback if the new host misbehaves

Expected outcomes

  • Per-server migration runbooks with owners and timing
  • Configuration and dependency checks before cutover
  • Validation and rollback steps after traffic moves

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

For some workloads using replication or load-balancer drain techniques. Others need a short maintenance window—we are explicit about which is realistic.

Linux is the primary focus. Windows server migrations can be included when part of the same project scope.
