Discovery First
Nothing moves until every dependency, licence and undocumented cron job has been found and written down.
Cloud Migration
Move to the cloud
without the maintenance
window nobody agreed to
- Dependency mapping first
- Rehearsed cutover, documented rollback
- Fixed-price migration waves
Most failed migrations were not technically hard. They were under-scoped. We spend the first two weeks finding what will break, so the cutover weekend is boring and reversible

HOW A MIGRATION RUNS
Three phases, and you can stop after any of them
01 — Assessment
Assess And
Assess And
Map
Two weeks of discovery: every workload inventoried, every dependency mapped, and a written target architecture with a cost model you can take to finance.
- Workload inventory & dependency map
- Target architecture & cost model
02 — Migration

Waves
Workloads move in small waves, lowest risk first. Each wave has a rehearsed cutover, a rollback that has actually been tested, and a go/no-go call you own.
- Pilot wave to prove the runbook
- Rehearsed cutover & tested rollback
03 — Optimisation

Hand Over
Lift-and-shift bills are always too high on day one. We rightsize, remove what nobody uses, then hand over documentation or keep running it for you.
- Rightsizing & cost cleanup
- Runbooks, handover or managed service

Why Migrate With Aura
The Boring Migration Is The Successful One
Surprises come from what you did not inventory. We front-load the discovery so the weekend everyone is dreading turns out to be uneventful.
Rehearsed Cutovers
We practise the switch on a pilot workload first, then run the real one against the same timed runbook.
Reversible By Design
Every wave has a tested rollback and a go/no-go call that you make, not us. Nobody gets trapped mid-cutover.

Estates We Have Moved, And What It Took
DATACENTRE EXIT
180 VMs out of a leased datacentre
Fourteen weeks from assessment to lease termination, moved in six waves, with 42 minutes of total planned downtime.
REPLATFORM
Monolith to managed Kubernetes
Rebuilt the runtime rather than lifting it, cutting the monthly bill by 34% and deploy time from hours to minutes.
DATA MIGRATION
9TB of regulated data, zero loss
Dual-write and reconcile rather than big-bang copy, with row-level verification signed off by the client's own auditors.
(Running production on Aura right now)

The Cutover Weekend
Track Record
Migration leadership backed by 240+ moved workloads
We have moved monoliths, mainframe-adjacent batch jobs, regulated databases and entire leased datacentres. That history is why our estimates hold: we have already met the thing that is about to surprise you.
- Lift-and-shift, replatform or rebuild - assessed, not assumed
- Regulated data migration with row-level verification
- VMware, bare metal, AWS, Azure and Google Cloud

Migration Questions
Frequently Asked Questions
For most workloads, minutes rather than hours - and you get the exact number from the pilot wave before the real cutover is booked. Where zero downtime is required we use replication and dual-write instead of a copy, which costs more but removes the window entirely.
Whichever the assessment justifies, per workload - it is rarely one answer for a whole estate. Lift-and-shift buys you a deadline, replatforming buys you the running cost. We show the maths for both and you choose.
Two weeks of assessment, then waves of one to three weeks each depending on blast radius. A 180-VM datacentre exit took us fourteen weeks end to end; a single application can be done in three.
The assessment is fixed price. Each migration wave is then quoted as a fixed price once we know what is in it - no day rates, no open-ended discovery. If a wave overruns because we mis-scoped it, that is on us.
