What is cloud migration?
Cloud migration is moving applications, data and infrastructure from on-premise servers or legacy hosting to a cloud platform. Each workload is rehosted, re-architected or left alone, depending on cost and benefit. We assess what you actually run, then sequence the move in stages so every step has a rollback and data integrity can be proven.
Cloud migration goes wrong in predictable ways: lifting an application unchanged and finding it costs more than the server it replaced, discovering an undocumented dependency during cutover, or moving data without a verified way to prove nothing was lost.
We work backwards from those failure modes. Assess what you actually run, decide per workload whether to rehost, re-architect, or leave it alone, and sequence the move so every step has a rollback and nothing depends on one perfect weekend.
What this includes
- 01
Infrastructure assessment
What you actually run, what depends on what, and what nobody documented.
- 02
Migration strategy
A per-workload decision — rehost, re-platform, re-architect, or retire.
- 03
Data migration
Moving data with verification, so completeness is proven rather than assumed.
- 04
Network and connectivity
VPNs, private connectivity, and hybrid setups during the transition period.
- 05
Staged cutover
Workload by workload with a rollback path at every step.
- 06
Post-migration tuning
Right-sizing and cost optimisation once real usage patterns are visible.
Situations we see most often
Ageing on-premise hardware
Servers approaching end of life, with a capital purchase otherwise due.
You cannot scale when you need to
Fixed capacity that cannot absorb growth or seasonal demand.
Disaster recovery is a weak point
Backups that have never been restored and no tested recovery plan.
Your current hosting is the constraint
A provider or setup that blocks the tooling and automation you want to adopt.
What to know before you start
Rehost, re-platform or re-architect: what is the difference?
Rehosting moves an application to the cloud largely unchanged, which is fast but rarely cheaper. Re-platforming makes targeted changes, such as moving a self-managed database to a managed one, for quick operational wins. Re-architecting changes how the application works to use cloud services fully, which costs more up front and delivers most of the long-term benefit.
We decide per workload. Some systems are best left where they are, and saying so is part of a proper assessment.
How is downtime avoided during migration?
By migrating in stages rather than in one weekend. Data is replicated to the new environment while the old one keeps running, traffic is shifted gradually, and every step has a tested rollback.
Most workloads move with brief, planned cutover windows, and some with none. We give you the expected window for each workload up front rather than promising zero downtime everywhere.
How do you prove no data was lost?
Data migration is treated as its own workstream. Before cutover we run trial migrations and reconcile counts, totals and checksums between source and target, and we keep rollback snapshots until the new environment has run cleanly.
The same checks run again at the final cutover, so the switch is backed by evidence rather than confidence.
What does the migration assessment produce?
An inventory of everything you run: applications, databases, scheduled jobs, file stores and the connections between them, including the undocumented ones. Each workload gets a recommendation to rehost, re-platform, re-architect or leave in place, with the reasoning and an estimated running cost in the cloud.
It also sets the order of migration, the expected downtime per workload, and the risks to watch. You own the assessment, whoever carries out the migration.
How is security handled in the new environment?
It is designed in, not carried over. Identity and access are set up with least privilege, networks are segmented, data is encrypted at rest and in transit, and secrets move into a secret manager. Infrastructure is defined as code, so the security configuration is reviewable and repeatable.
Migration is often the best moment to fix access problems that have built up over years in the old environment.
What drives the cost of a cloud migration?
Migration cost depends on what you run today and how much each workload changes on the way. These factors move it most.
| Factor | Effect | Why it matters |
|---|---|---|
| Number of workloads | High | Every application, database and scheduled job needs assessing, planning and moving. |
| Migration approach | High | Rehosting is quickest; re-architecting costs more now and usually lowers running costs later. |
| Data volume and sensitivity | High | Large or regulated datasets need replication, verification and residency planning. |
| Undocumented dependencies | Medium | Hidden connections between systems found during assessment add work, and are far worse to find during cutover. |
| Downtime tolerance | Medium | Near-zero downtime needs replication and gradual traffic shifting rather than a simple cutover window. |
| Post-migration tuning | Low | Right-sizing and cost tuning after the move is quick work with a large effect on the monthly bill. |

Questions we get asked
01Will migration cause downtime?
Usually minimal, and planned. Most workloads migrate with brief cutover windows, and some with none using replication and traffic shifting. We tell you the expected window per workload up front rather than promising zero and discovering otherwise.
02Will the cloud be cheaper?
Not automatically, and anyone promising it is guessing. Lift-and-shift often costs more than the hardware it replaced. Savings come from re-architecting to use managed services and scaling down when idle — which is why we model cost during planning.
03What about data residency requirements?
All major providers offer Indian regions, and residency requirements are part of the planning input rather than an afterthought. Where regulation demands specific handling, we design to it explicitly.
04Can we migrate in phases?
Yes, and we recommend it. Lower-risk workloads usually move first, so your team gains experience before the critical systems move.
05Do you migrate databases as well as applications?
Yes, including moving self-managed databases to managed services where that makes sense, with verification at each stage.
06Can you help us choose a cloud provider?
Yes. The assessment compares providers against your workloads, existing licences, team skills and data residency needs, rather than defaulting to one.
07What happens after the migration?
Tuning and handover: right-sizing resources once real usage is visible, setting cost alerts, documenting the new environment, and optional ongoing operations support under a maintenance retainer.
08Do you migrate email and office systems?
Our focus is applications, databases and the infrastructure behind them. For email and office suites we work alongside specialists, and make sure your applications keep working through the change.
