Azure & Microsoft Migration

Azure migration, assessed before it is promised.

Most migration projects do not fail during the migration. They fail four months earlier, when someone estimated the work by looking at a server list.

Migration proceeds in waves, smallest blast radius first. Every wave is rehearsed before it is allowed to cut over.

We start with an assessment: a fixed-scope, fixed-price review of what you actually run, what it depends on, what it will cost in Azure, and what will hurt. You get a costed plan and a risk register. Then you decide whether to migrate at all — with us, with your own team, or with somebody else.

What this silo does not cover, stated plainly rather than left to the rail alone: we do not issue regulatory audits, compliance attestations or signed opinions. We build and document environments that stand up to those reviews; an audit firm or a PCI QSA issues the opinion.

What you are actually buying

Risk you can see before you accept it

Every assessment produces a written risk register: what could go wrong, how likely, what it would cost you, and what we would do to reduce it. Items we cannot resolve stay on the register as open risks with your name against the acceptance — they do not get quietly dropped because they are inconvenient.

The risks that actually bite in this segment are boring and predictable: an undocumented dependency on a server that was not in scope, a licence that does not travel, an application whose vendor will not support it in Azure, a backup that has never been restored, and a firewall rule that only one person understands. We go looking for those in the assessment, because finding them during a cutover is what turns a weekend into a fortnight.

Downtime you scheduled, not downtime you discovered

Every workload in the plan gets a migration method, a rehearsal, a stated downtime window and a rollback that has been tested rather than described.

Most workloads move with minutes of downtime using replication-based methods that keep the source running until you cut over. Some cannot — a large database on a thin network link, or an application that must be reinstalled rather than moved. Those are identified in the assessment and priced honestly, in hours, before you commit to a date. You approve every window in advance.

If the rehearsal fails, the cutover does not happen. That is the rule, and it is written into the plan rather than negotiated at midnight.

A cost you can defend to a CFO

Azure is not automatically cheaper than what you run today. Anyone who tells you otherwise on a first call has not looked at your estate.

What Azure does reliably give you is cost you can see, attribute and change — which is often the more valuable property. The assessment produces a monthly run-rate estimate built from your actual utilisation rather than your server specifications, because most on-premises servers are sized for a peak that happens twice a year.

We model the levers explicitly and show you what each one is worth:

Azure cost levers and when each one applies
LeverWhat it doesApplies when
Right-sizingMatch resources to observed use, not to the tin you bought in 2019Almost always; usually the single largest saving
Reserved instances / savings plansCommit to a term for a lower rateSteady-state workloads you are confident about
Azure Hybrid BenefitApply existing Windows Server or SQL Server licences to Azure ratesOnly if you hold active Software Assurance or equivalent subscriptions
Non-production schedulesShut down dev and test outside working hoursWherever a non-production environment exists
Storage tieringMove cold data off premium storageEstates with large archives or long retention
PaaS instead of VMsRemove OS licensing, patching and upgrade effortWhere the application supports it — see SQL Server to Azure SQL

You also get the number nobody volunteers: the one-time cost of the migration itself, separated from the run-rate, so the business case is not quietly subsidised by leaving the project cost out of it.

Compliance questions you can answer in an afternoon

Finance and retail buyers do not get to treat access control as a technical detail. Sooner or later somebody asks who could reach production data, when, and on whose authority — an auditor, a large client's vendor-risk team, a card processor's questionnaire, or an incident.

We build environments where that question has a report as its answer:

What we migrate

What this silo covers

What the engagement looks like

  1. Assess. Read-only. We inventory what you run and what it depends on — servers, databases, applications, network paths, identity, licensing, backups — and hand back a dependency map, a workload-by-workload recommendation, a costed run-rate, a risk register and a wave plan.

  2. Plan. We turn the recommendation into a landing zone design: subscriptions, networking, identity, guardrails, backup and disaster-recovery targets, defined as code in your repository from day one.

  3. Migrate. In waves, smallest blast radius first. Each wave is built, replicated, rehearsed, cut over inside a window you approved, then run in parallel until you sign off.

  4. Run. For the first month after the final cutover we sit alongside your team, then hand over documentation, the infrastructure code, and a runbook — not a PDF and an invoice.

Built for

  • 15 to 500 employees, in finance or retail, in the United States.
  • A deadline that is real: a support date passing, a hosting contract expiring, hardware out of warranty, an audit finding, or a peak season you cannot risk.
  • An estate of a handful to a few dozen servers, typically Windows Server and SQL Server.
  • Microsoft 365 already in use, or about to be.

Not a fit

  • You need a regulatory audit, an attestation, or a signed compliance opinion — we build environments that stand up to those reviews, we don't issue the opinion.
  • You run thousands of servers or a global estate — a large systems integrator is the right shape of firm for that.
  • You want a lift-and-shift by Friday with no assessment.
  • Your only driver is "the board wants a cloud strategy" with no operational problem underneath it — the assessment will probably tell you to stay where you are, and we will still charge for saying so.

Two pages worth reading before the call:

Questions buyers actually ask

Will the business be down?

Some, briefly, and you will know when.

Most workloads move with minutes of downtime, using replication that keeps your current environment running until the moment you cut over. Some genuinely cannot — a very large database over a constrained link, or an application that has to be reinstalled and reconfigured rather than replicated. Those are identified during the assessment, priced in hours, and scheduled with you.

Three commitments: you approve every downtime window in advance; every cutover is rehearsed first; and every cutover has a tested rollback. If the rehearsal does not pass, the cutover does not happen.

SQL Server 2016 is out of support. Does that mean we have to move to Azure?

No — and this is worth getting right, because the usual pitch is wrong.

SQL Server 2016 reached end of extended support on 14 July 2026. Extended Security Updates are available for up to three years after that, until 17 July 2029.

You will hear that migrating to Azure gets you those updates free. That is not true for SQL Server 2016. Microsoft's own documentation is explicit: "Starting with SQL Server 2016 (13.x), migrating your workload to SQL Server on Azure VMs no longer provides free access to ESUs for SQL Server 2016 (13.x) instances." That benefit existed for SQL Server 2014. It does not carry forward. If a vendor uses free ESUs as the reason to move your 2016 estate to Azure VMs, they are working from an old deck.

Your real options are four: upgrade in place, subscribe to Extended Security Updates, rehost to Azure VMs, or re-platform to Azure SQL Managed Instance or Azure SQL Database. Which is right depends on your application's compatibility, your licensing position, and whether you would rather spend money once or annually.

The full option-by-option breakdown — including the two options that are not an Azure migration at all — is on SQL Server to Azure SQL.

Is Azure actually going to cost us less than what we run now?

Sometimes, and not always, and you should be suspicious of a firm that promises a percentage before seeing your utilisation data.

Here is the honest version. If you compare a like-for-like rehost of over-provisioned servers against already-depreciated hardware, Azure often looks more expensive on the monthly line. The comparison usually turns when you include what the current setup actually costs: hardware refresh, hypervisor and OS licensing, datacenter or hosting, power, the disaster-recovery site you pay for and hope never to use, and the engineering time spent on maintenance that produces nothing.

It also turns on right-sizing. Most on-premises servers are specified for a peak that occurs twice a year, and you paid for that peak in advance and permanently. In Azure you pay for what you use, and can change it in an afternoon.

The assessment gives you a run-rate estimate from observed utilisation, the one-time migration cost, and the levers in the table above with a value against each. If that comparison does not favour moving, it will say so.

Do we have to move everything at once?

No, and you should not.

We sequence in waves, and the first wave is deliberately chosen for low risk and easy reversibility — something that matters enough to be a real test, but whose failure would not stop the business. That first wave is where you find out whether the plan was any good and whether you want to keep working with us, at the smallest possible cost of finding out.

Many estates end up permanently hybrid, and that is a legitimate destination rather than a failed migration. Some workloads should not move: a system whose vendor does not support it in Azure, a machine tied to physical hardware, or something being replaced in eighteen months anyway. The assessment says which, and why.

Start with the assessment, not the migration.
