Move workloads off bare metal into any cloud, or shift an existing estate from one cloud platform to another — planned as a reversible, wave-by-wave programme, cut over inside a maintenance window measured in minutes, and independently audited once it lands so no temporary access grant or loosened rule is left behind.
What's included
Whether you are leaving a data centre or leaving a hyperscaler, the discovery, design, and cutover discipline is the same.
Physical and co-located servers, VMware, and on-prem hypervisors lifted into AWS, Azure, GCP, or a sovereign/regional cloud — rehosted as-is where speed matters, replatformed onto managed compute, storage, and networking where it pays off.
Rehost · ReplatformAWS ↔ Azure ↔ GCP and beyond: every managed service mapped to its equivalent (or a portable replacement), IAM and network policy re-modelled per target, and egress, data-transfer cost, and region strategy worked out before the first byte moves.
Service parity mappingAn inventory of every server, service, cron job, shared mount, and hard-coded hostname, grouped into move-groups by dependency so nothing is discovered missing mid-cutover.
DiscoveryTarget VPC/VNet layout, subnetting, routing, private connectivity, and firewall rules designed for least exposure; block, object, and file storage remapped; SSO, service accounts, and key management rebuilt on the target's primitives.
Target architectureContinuous replication, pre-warmed target, DNS/traffic weighting, and a scripted go/no-go runbook — plus a tested rollback path that returns traffic to source in minutes if a check fails.
Runbook · RollbackThe target environment is delivered as Terraform / OpenTofu and pipeline config, not console clicks — so it is reproducible, reviewable, and the staging and production estates cannot quietly drift apart.
Terraform · CI/CDHow we de-risk it
Agent-based and agentless discovery builds a live map of hosts, processes, open ports, traffic flows, and storage — the baseline everything else is measured against, and the artefact that catches the “we forgot that box existed” server before it becomes an incident.
Each workload gets a disposition — rehost, replatform, retire, or retain — and workloads are batched into waves that can each be migrated, validated, and if necessary rolled back on their own.
Block-level or file-level replication keeps the target continuously in sync. A low-risk pilot wave proves the tooling, the runbook, and the validation checks on real workloads before anything customer-facing moves.
Cutover runs to a timed checklist: freeze, final sync, flip traffic, run automated smoke and security checks, then confirm or roll back. Rollback is a first-class path, not an afterthought.
A separate review checks the landed environment against CIS / cloud best practice: public exposure, IAM sprawl, unencrypted volumes, permissive security groups, and any “temporary” access opened during the move.
Source systems are wiped and retired on a schedule, cost and right-sizing recommendations are handed over, and your team gets the IaC, runbooks, and diagrams to own it going forward.
Why it matters
Rushed cutovers, copied-forward firewall rules, over-broad IAM roles created “just to get it working”, and storage buckets made public for a one-off data copy are how most cloud exposure actually starts — not through exotic attacks, but through change made under time pressure with no independent check.
Running the migration and an independent audit as one engagement closes that window instead of leaving it open. The team that designs the target architecture does not get to mark its own homework: the audit is a distinct, honest pass that confirms the new environment is at least as defensible as the one it replaced.
What to expect
Discover the estate, map dependencies, and agree the disposition and wave plan for every workload.
Network, identity, storage, and compute architecture as reviewable infrastructure-as-code, with security defaults baked in.
Replicate, run a pilot wave, then move the rest in batches — each one validated before the next begins.
Timed cutover with a live rollback path, then an independent audit and a clean handover to your team.
