What they don’t tell you about cloud migrations…

Like a lot of organisations (yes, a lot as the cloud curve really isn’t as advanced as some would have it) you find yourself facing up to the reality of a chunk of technical debt. It’s probably that classic hybrid of on-prem and hosted systems and it’s led you to your latest strategic decision - your next move is migrating to the cloud.

And, because it’s such a prevalent myth, you’re already framing your cloud migration as a technical exercise. Move workloads. Stand up landing zones. Rehost, refactor, rebuild. Job done, well done us!

Of course, the reality is somewhat different - most migration projects succeed or fail long before the first workload moves. In our experience, those that get real value from Azure treat migration as a business transformation programme, not a lift-and-shift task.

And, trust us, that makes all the difference!

The real challenges of migration

By the time an organisation commits to Azure, they’re usually clear on the why: agility, resilience, scalability, innovation. What’s less clear is the how.

Let’s look at the typical stumbling blocks.

Underestimating complexity

Very few estates are clean. Hidden dependencies, undocumented integrations, legacy authentication methods, licensing surprises, they don’t always make it onto the planning diagrams.

Without deep discovery and expert due diligence, what looks straightforward on paper can introduce operational risk or spiralling cost once moved. Nothing to do with Azure, everything to do with a lack of understanding.

Treating migration as a one-off event

Migration is a major effort so you can’t blame people for seeing it (wishing it!) as a finite project with a fixed end date. But that can skew the focus on just getting to the arrival point, whereas what you really need to fix on arriving or landing in the right shape.

An Azure estate that mirrors on-prem inefficiencies and latent legacy issues isn’t modernisation, it’s simply relocation.

To counter that risk, keep these critical success factors in mind:

• Design governance early

• Establish identity and security correctly

• Align workloads to cost models

• Build with optimisation the aim from day one

Technical debt can travel really quickly and weigh heavily for years so it is worth taking the time and effort to plan it out.

Misjudging internal readiness

Expect a different operational rhythm with Cloud. FinOps discipline. Continuous optimisation. Security posture management. Platform engineering practices. DevOps integration. If internal teams are already stretched, adding this new operating model on top can create unwanted and unhelpful friction. That drag can see organisations quietly plateau; they may have technically migrated, but are still a long way short of being strategically transformed.

What doing it well actually looks like

 Analyse successful migrations and you’ll soon spot some consistent characteristics.

Clarity of outcome

They start with business intent. Not ‘move 120 VMs’ but ‘enable faster product release cycles’ or ‘reduce infrastructure spend by 20%’ or ’increase resilience for customer-facing systems.’ You’re aligning technology to measurable commercial outcomes.

Structured discovery

Deep, diligent estate assessment. Dependency mapping. Licensing analysis. Workload profiling. All findings, especially the uncomfortable ones, are what prevent expensive mistakes later.

Designed landing zones

Governance, policy, security, identity, monitoring and cost management are embedded before workloads move, not retrofitted or shoehorned in later.

Phased, evidence-based execution

Early waves validate assumptions; lessons learned allow for tweaks and pivots before errors and miscalculations get baked in. Optimisation also begins immediately, not six months after go-live.

Where specialist expertise makes the difference

The power and potential of Azure is, well, probably only limited by one’s imagination. But this is hyperscale computing so it’s very big, broad, evolving, and nuanced.

That can be challenging for the average internal team who won’t have experienced dozens of migrations across multiple sectors. They won’t have encountered the unusual edge cases, the licensing anomalies, the architecture trade-offs that don’t show up in documentation.

Specialists who have been exposed to so much more in this space will bring: 

• Pattern recognition from previous migrations

• Practical solutions to common (and uncommon) blockers

• Commercial awareness around cost structures

• Hard-won experience of what not to do

Harness those specialists and you can be confident of accelerating learning curves and reducing risk. And when something unexpected does emerge – and it’s always when rather than if! - you want people in the room who have seen it before.

Migrating well

A migration window is a rare opportunity to rethink architecture, governance and cost models, to modernise and optimise with the full company buy-in. Handled well, it can become a powerful springboard for growth and innovation; handled poorly, it just becomes an expensive and frustrating hosting change.

Perhaps the thing to keep in mind above all is that migration should never be seen simply as moving, but improving.

Done right, migration is the start of transformation. Shaping Cloud helps organisations design, migrate and optimise Azure environments that are built for the future.
