One of the first mistakes councils can make is defining success too narrowly. The conversation can quickly become focused on which platform to move to, how quickly systems can be consolidated and when legacy environments can be switched off.

But migration itself isn’t the objective. Creating a stronger organisation is.

The goal should be to build a council that collaborates more effectively, serves citizens better, reduces duplication and improves visibility, while operating securely and preparing for AI-enabled ways of working.

If councils focus solely on moving technology, there is a risk of simply recreating existing inefficiencies within a larger structure. Instead, migration should be viewed as an opportunity to rethink how the new organisation operates and what it needs to achieve.

Planning should therefore start with a simple question:

“What kind of organisation are we trying to become?”

The answer should shape every migration decision that follows, from technology and data to processes, governance and the experience of staff and citizens.

Almost every council underestimates the importance of discovery, often because they assume they already understand their environment.

Then the real work begins, and the gaps start to emerge. Duplicate databases, disconnected systems, historic SharePoint environments, inconsistent permissions, legacy integrations and operational spreadsheets that no one knew existed can quickly turn a straightforward migration into a much more complex challenge.

It’s a bit like preparing to move house and discovering half the contents of the loft were never documented in the first place.

That’s why discovery isn’t simply an IT exercise. It’s operational risk management.

Councils need a clear picture of what systems and data exist, which services depend on them, where duplication sits, what needs to be retained or archived, and where governance gaps could create risk.

Without proper discovery, migration planning becomes guesswork. And when you’re bringing organisations together, guesswork can be costly.

Citizens don’t experience local government through systems. They experience it through services.

They care about whether their housing needs are addressed, planning applications progress, waste is collected, safeguarding is effective and support is available when they need it. They don’t care which platform sits behind those services, they care that they work.

That means councils should plan migration around operational continuity first, rather than around whichever technology is easiest to implement.

A good planning process should identify which services are most critical, which teams are most exposed to disruption, what citizens would notice immediately if something failed and where the greatest operational dependencies sit.

Technology decisions should support those priorities, not replace them.

Because ultimately, the success of reorganisation will be judged by one thing: whether citizens continue receiving reliable services throughout the change.

One of the easiest things to underestimate during planning is the human impact of reorganisation. Yet staff are often under enormous pressure throughout the transition, expected to continue delivering services while adapting to new structures, learning new platforms, working with unfamiliar colleagues and navigating uncertainty.

Without the right support, even well-designed transformation programmes can struggle. That’s why successful councils prioritise clear communication, visible leadership, effective onboarding and training, ongoing adoption support and opportunities for staff to provide feedback.

Because people don’t resist change simply because systems are difficult. They resist when they feel unsupported, uncertain or unclear about what comes next.

Transformation should feel guided, supported and purposeful, not imposed.

Ultimately, successful reorganisation planning isn’t about creating the most ambitious programme. It’s about reducing friction, for citizens, staff, leadership, governance and day-to-day service delivery.

The councils that succeed are rarely those that simply move fastest. They are the ones that take the time to understand their environment, simplify intelligently, phase change realistically and establish clear governance, while keeping operational continuity at the centre of every decision.

Because reorganisation isn’t simply about bringing organisations together. It’s about creating one that can operate more effectively than those that came before it.
