Cloud migration planning for Japanese regions
Migration Roadmap · ¥30,500

A written plan for moving workloads to Japanese cloud — one careful step at a time.

A planning engagement for teams who want to approach cloud migration as a series of considered decisions rather than a single, pressured transition event.

What this delivers

A written roadmap with candidate phases, decision points, and no obligation to follow any of it on a fixed schedule.

When the engagement closes, you'll have a written roadmap describing how a transition from your current on-premises environment into Japanese cloud regions could be structured — which workloads are reasonable candidates for early phases, where the dependencies and data residency considerations sit, and what decisions need to be made at each stage before proceeding.

The roadmap is a planning document, not a contract. It describes options and decision points. What you do with it — and when — is entirely your team's call.

Workload inventory

A structured account of what's running, what it depends on, and how each workload relates to the question of cloud candidacy.

Dependency and residency mapping

Where data needs to stay, what can move independently, and which dependencies constrain the sequencing of any transition phases.

Written roadmap with phases

Candidate migration phases described in sequence, with the decision points your team will need to work through before beginning each one.

Where teams often find themselves

You know migration is probably coming. You're not sure where to begin — or whether the timing is right.

Most teams considering a cloud transition aren't starting from zero. They have workloads they understand reasonably well, infrastructure they've maintained for years, and a general sense that moving some of it to the cloud would be sensible at some point. What they don't have is a clear picture of which workloads to move first, what the dependencies look like, and how to sequence the transition without destabilising what's already running.

Without a written plan, migration decisions tend to get made reactively — when a hardware refresh forces the question, or when someone decides a particular service should move because it would be simpler. That approach works, but it rarely produces the most considered outcome. A planning document doesn't remove the complexity. It makes the complexity visible earlier, when there's still time to decide calmly.

No clear view of which workloads are reasonable cloud candidates and which ones carry hidden dependencies that complicate the decision.

Data residency requirements that need to be worked through before any transition can begin — but haven't been mapped against the workload inventory yet.

Pressure to make migration decisions without a written framework that the whole team — not just the most senior technical staff — can refer to.

Uncertainty about Japanese cloud region specifics — availability zones, service coverage, and how those factors affect which workloads can move when.

Our approach

We start with what you have, map what matters, and write a plan your team can actually follow.

The Cloud Migration Roadmap engagement moves through three phases. We begin with a workload inventory — documenting what's running, how it's configured, and what it connects to. We then work through dependency and data residency considerations, which typically reveal both the natural early migration candidates and the workloads that should move later or not at all. The engagement closes with a written roadmap describing candidate phases in sequence, with explicit decision points at each transition.

All of this is oriented around Japanese cloud regions specifically — their characteristics, service availability, and the data residency requirements that apply to workloads operating under Japanese regulatory context.

Workload inventory

A structured account of what's currently running on-premises, how each workload is configured, and what it depends on — the foundation everything else builds from.

Dependency analysis

Tracing the connections between workloads to identify which ones can move independently and which have constraints that affect when and how they can transition.

Data residency review

Mapping data residency requirements against the workload inventory — identifying what needs to stay within Japanese infrastructure and how that affects the migration options available.

Written phased roadmap

A document describing candidate migration phases in sequence — what moves in each phase, why, what decisions need to be made first, and what a reasonable timeline looks like for each step.

What working together looks like

A structured engagement built around three clear phases.

Phase 1

Workload inventory

We work with your team to document the current on-premises workload landscape — what's running, what role it plays, and how it's configured. This phase produces the inventory that all subsequent planning builds on.

Phase 2

Dependency and residency mapping

Working from the inventory, we trace dependencies between workloads and map data residency requirements against the available Japanese cloud region options. This is where the realistic migration sequencing becomes clear.

Phase 3

Roadmap writing and delivery

We write the roadmap — candidate phases, decision points, and the reasoning behind the recommended sequencing. Your team reviews a draft, we incorporate corrections, and the final document is delivered with a walkthrough session.

Investment

One fixed fee. A complete planning document your team owns outright.

The Cloud Migration Roadmap is priced at ¥30,500. That covers the full engagement — workload inventory, dependency and residency mapping, roadmap writing, draft review, and final delivery. No hourly billing and no additions that arrive at invoice.

The roadmap is yours entirely. If you decide to act on it later, with a different team or a different approach, that's a perfectly reasonable outcome. The document is a planning resource, not a commitment to continued engagement with us.

Why planning first makes sense

Migration decisions made without a written plan tend to cost more to reverse later.

Teams that approach migration incrementally — with a documented inventory and a sequenced roadmap — typically find that the early phases go more smoothly than those that start from a general intent to "move things to the cloud." The planning work surfaces the constraints early, when there's still time to adjust the approach. A written roadmap doesn't guarantee a smooth migration, but it does mean the team is working from the same shared understanding rather than each person's private mental model of how the transition should proceed.

JP regions

All planning is oriented around Japanese cloud regions specifically — their service availability, availability zone characteristics, and the data residency considerations relevant to operations here.

Decision-led

The roadmap is structured around decision points, not just tasks. Each phase transition depends on specific decisions being made — so your team always knows what needs to be resolved before the next step begins.

No lock-in

The roadmap describes options. Following it doesn't require continuing to work with us. Use it with your own team, with another partner, or adapt it as your situation evolves — it belongs to you.

Our commitment

If migration planning isn't actually where your team is, we'll say so rather than produce a document that doesn't fit your situation.

The initial conversation is where we work out whether this engagement is a reasonable fit. If your team is still in the early stages of understanding your current estate — before a migration conversation makes sense — we'll be direct about that. The Architecture Review or Server Infrastructure Documentation engagement might be more useful first. We'd rather make that recommendation early than deliver a roadmap that doesn't have a solid foundation to build from.

Reaching out doesn't commit you to anything. A short description of where your team is with the migration question is enough to start a useful conversation.

Honest assessment of fit before the engagement begins — no pressure to proceed if the timing isn't right.

Fixed price with scope agreed in writing before we start — no billing surprises at delivery.

Draft review included — your team can correct factual errors in the workload inventory and roadmap before the final version is delivered.

Complete document ownership — the roadmap and inventory belong to your team with no access restrictions or continued engagement required.

Getting started

A short description of where your team is with the migration question is enough to begin.

You don't need a prepared brief or a clear migration plan already in place — if you had those, you wouldn't need this engagement. Write us a short note describing roughly what your on-premises workload environment looks like and what you're trying to work out. We'll follow up within a couple of working days with a direct response and, if it seems useful, a time to talk.
