Cloud Migration Services: Costs and Scope

What Cloud Migration Services Include and What They Cost

Cloud migration services move your applications, data and workloads from servers you own or rent into a cloud platform, with planning and testing for their continued operation. A properly scoped engagement covers far more than copying files across. It usually includes discovery (what you run today, who uses it and what depends on what), a migration design, the cutover itself, testing, and a stabilisation period before the old environment is switched off. Ask which of these stages is included in the proposal.

There is no single price that fits every migration. The number of systems, data volumes, integrations, downtime tolerance and amount of redesign can change the scope. Request an itemised quote in AUD with GST treatment, assumptions and exclusions stated. This guide does not offer a market average or a Bestcomm price estimate.

When you ask for a quote on cloud migration services, ask what's inside it. Is discovery separate? Does it include testing, user training and a rollback plan? Who pays for running the old and new environments in parallel? And what will it cost each month once you're live? Cloud consumption is a recurring bill, not a one-off project. A quote that can't answer these questions is a number, not a scope.

Migration Approaches Compared: Rehost, Replatform and Refactor

Migration proposals may use terms such as rehost, replatform and refactor. Ask the provider to explain what each means for your specific systems and to compare it with retaining or replacing the workload.

• Rehost: What can move with limited application changes, and what dependencies must still be tested?
• Replatform: Which platform components would change, and who would own maintenance and backup tasks afterwards?
• Refactor: What application redesign is proposed, why is it needed, and what additional development and testing does it require?
• Retain, retire or replace: Does the workload need to move at all? Confirm business, record-retention and dependency needs before retiring anything.

Do not assume one approach is always fastest, cheapest or lowest risk. Ask for the reasoning, estimated effort and acceptance checks for each workload.

Data Location and Access Questions

Ask providers to document where production data and backups will be stored, who can access them and which subcontractors will be involved. Review those answers against your organisation’s contracts, information-handling needs and any requirements confirmed by your adviser. An Australian hosting-region label is not, by itself, a compliance assessment.

Before selecting a service, ask your security and legal advisers what evidence or assessments your particular workload requires. Do not assume that one cloud region, certification or vendor description is suitable for every sector.

For data-breach planning, consult the OAIC’s official guidance. For security planning, use the official Essential Eight guidance with an adviser who can assess your environment. This article does not determine legal applicability or prescribe a maturity level.

If local hosting is relevant, ask which locations are available for production, backup and recovery rather than assuming all data remains in one place.

Where Migrations Go Wrong and What to Scope Before You Sign

Before signing, ask how the proposal addresses incomplete inventories, undocumented dependencies, cutover timing and support ownership.

Discovery that is real. You want an inventory of applications, data, integrations, users and licences, plus a clear list of what will be migrated, replaced, retained or retired. If a quote skips discovery or buries it, expect surprises mid-project. This is also where you decide what you're migrating for: cost, resilience, remote access, a deadline.

Downtime and rollback. Ask what happens if the cutover fails. A credible plan names the cutover window, explains how the business operates during it, and describes how you return to the old environment if needed. Ask your technical lead to define safe rollback conditions and when the old environment can be retired; leaving two systems active can also create data-consistency and cost issues.

Dependencies. Ask whether phones, printers, scanners, access systems, accounting integrations and scheduled jobs depend on anything being moved. Include the relevant system owners in planning and acceptance checks. This is a discovery checklist, not an instruction to change those systems.

Ownership after go-live. Who holds the administrator credentials, the licences and the cloud account itself? The account and credentials should be in your business's name, with the provider given delegated access. Without that, leaving a provider later can be painful. Ask for documentation as a deliverable.

Security and continuity. Ask your technical adviser to document identity, access, backup and restore-testing arrangements as part of the design. Agree responsibilities and the evidence required before approving cutover.

Exit and running costs. Ask about egress charges for moving data out, minimum terms and notice periods, and what repatriation would involve. We haven't gathered figures on these, so don't assume they're cheap or free; ask for them in writing.

Compare proposals with an acceptance worksheet

Ask each supplier to work from the same workload inventory. For every workload, record its business owner, proposed destination, dependencies, exclusions and the evidence needed before acceptance. Mark unanswered questions as unresolved rather than assuming they are included in a fixed price. If discovery is a separate engagement, ask what documented findings you will receive even if you decide not to proceed with migration.

A useful acceptance worksheet separates technical checks from business checks. The technical owner can define appropriate access, backup and monitoring tests. The business owner can identify a representative activity that must work, such as finding an authorised sample record or completing a test transaction in a safe environment. Neither a successful file copy nor an accessible login page proves that the whole workflow is ready.

Agree who records results and who may authorise cutover. Document how unresolved issues are prioritised and which ones prevent acceptance. Have the technical team define any rehearsal and rollback arrangements for the actual environment; this guide is not a set of steps for moving production data or changing live infrastructure.

Budget for the operating arrangement, not only the move

Request a written description of ongoing ownership after stabilisation. Ask who monitors usage, reviews exceptions, approves changes and provides support when a dependency is outside the hosting provider's control. Confirm what happens when the named contact is unavailable and which services require separate agreements.

Compare the proposed recurring bill with a documented current baseline. Include overlapping transition costs and identify estimates separately from contractual prices. A lower infrastructure line does not establish a lower total cost if support, licences or internal effort have moved elsewhere. Agree how usage changes will be reviewed without assuming a guaranteed saving.

Bestcomm's hosting and data-centre service describes workload, continuity and ownership scoping. Its cybersecurity service covers related risk and response questions. Confirm the actual responsibilities in the written proposal rather than treating either service page as the terms of your project.

How to Choose a Cloud Migration Provider and Next Steps

Use concrete criteria rather than brand familiarity.

• Scope clarity. Can they show a written scope with discovery, design, migration, testing, cutover and stabilisation as separate items, each with an owner?
• Method fit. Do they assess each workload against rehost, replatform, refactor and retire, or push one approach?
• Residency and sovereignty answers. Can they explain, in plain English, where your data will live, who can access it and how that matches your contracts and privacy duties?
• Ownership terms. Will the cloud account, licences and credentials sit in your name, with documentation handed over?
• Exit terms. Are minimum terms, notice periods, egress and handover stated up front?
• Joined-up delivery. Who coordinates changes that affect communications, security and hosting? Ask for one named coordination role and a written split of responsibilities.
• Evidence over claims. Ask suppliers to explain any savings estimate and test its assumptions against your own current costs and proposed usage. Do not treat an estimate as a guaranteed outcome.

Next, gather a non-sensitive inventory of your systems, users, contract end dates and confirmed requirements. Bestcomm works with businesses in Melbourne and Victoria; other Australian locations are by agreement. Contact Bestcomm Australia to discuss your scope. Do not include passwords or confidential records in an initial enquiry.
