For many UK SMEs, modernisation is not a clean break between “old IT” and “new IT”. It is a carefully governed transition between systems that have supported the business for years and platforms designed for the next stage of growth.
That is particularly true for organisations running IBM i Management environments alongside Microsoft 365, cloud applications and emerging Dynamics 365 requirements. Retailers, accountants, healthcare providers, freight operators, education providers and financial services businesses cannot simply switch off a dependable core system and hope for the best.
The better approach is strategic: understand the current estate, define the future operating model, protect continuity and move in controlled stages.
This is where a consultancy-first approach matters. The role is not simply to sell software, install hardware or provide a ticket-based service desk. It is to act as the organisation’s Fractal IT Director: connecting commercial objectives, risk, compliance, systems and infrastructure into one practical technology strategy.
Modernisation should begin with business outcomes
Moving from a legacy platform towards Dynamics 365 is not, in itself, a business strategy. It is a potential enabler for one.
The starting questions should be commercial and operational:
- Which processes are slowing growth?
- Where is staff time being lost to duplication or manual rekeying?
- Which data must be available for timely decisions?
- What would happen if a critical system became unavailable for 24 hours?
- Which technology costs are essential, duplicated or no longer delivering value?
- What evidence would customers, insurers, auditors or regulators expect to see?
For some organisations, the right answer may be a phased move to Dynamics 365 Business Central. For others, it may be continued investment in a well-managed IBM i estate with modern integrations around it.
The objective is not to modernise for modernisation’s sake. It is to create a resilient, supportable and economically rational IT estate.
Treat the existing estate as an asset, not an embarrassment
Specialist IBM i Management remains a high-value consultancy discipline. These environments often contain decades of operational knowledge, carefully developed processes and business-critical data.
They may also be difficult to document, dependent on specialist skills or connected to systems that were designed long before today’s cloud services existed. That does not automatically make them unsuitable. It does mean they require a proper assessment.
A strategic review should map:
- Core applications and business processes
- Data ownership, retention and quality
- Interfaces with finance, warehousing, payroll or customer systems
- User access and privileged accounts
- Backup, recovery and high-availability arrangements
- Hardware, software and support dependencies
- Regulatory, contractual and insurance requirements
- The cost of maintaining the platform compared with viable alternatives
This analysis creates three possible pathways:
- Optimise the existing platform where it remains effective and economical.
- Integrate and coexist while selected functions move to Dynamics 365.
- Replace components progressively once the target system has been tested and accepted.
The important point is that the decision should be made through evidence, not fashion.
ISO 27001 and Cyber Essentials: practical consultancy domains
Compliance should not be treated as a certificate acquired at the end of a technology project. It should shape the project from the beginning.
For UK SMEs, Cyber Essentials provides a recognised baseline for protecting systems against common internet-based threats. Its control areas include firewalls, secure configuration, user access control, malware protection and security update management. The National Cyber Security Centre guidance on Cyber Essentials is a useful starting point.
Cyber Essentials is not a complete business continuity framework, nor is it a substitute for a risk-led information security programme. It is a foundation.
ISO 27001 provides a broader structure through an Information Security Management System. It encourages organisations to identify and manage risks across people, processes, suppliers, information and technology. For a business operating both legacy infrastructure and cloud platforms, that wider view is essential.
Consultancy support in this area may include:
- Defining the scope of the information security programme
- Building an accurate asset and data inventory
- Completing risk assessments and treatment plans
- Reviewing supplier and cloud service dependencies
- Establishing access control and privileged-access principles
- Creating incident response and continuity procedures
- Aligning policies with operational reality
- Preparing evidence for an independent assessment
Neither framework should be approached as a paperwork exercise. A policy that does not reflect how staff actually work is not a control; it is decoration.
Disaster Recovery is a business decision
Disaster Recovery is often discussed as a technical backup problem. In reality, it is a business continuity decision involving customers, employees, suppliers, cash flow and reputation.
A robust Disaster Recovery programme should identify:
- Which processes are critical to daily operations
- How long each process can be unavailable
- How much data the business can afford to lose
- Which systems and suppliers each process depends on
- What manual workarounds exist during an outage
- Who is authorised to make recovery decisions
- How recovery procedures will be tested
This is especially important during a transition from IBM i to Dynamics 365. A business may need to protect two operating models at once: the established platform that currently runs key processes and the developing cloud estate that will eventually take on more responsibility.
Recovery objectives should therefore be defined for the whole service, not just individual servers or applications. A finance team may be able to access an application, but still be unable to operate if identity services, integrations, telephony or document storage are unavailable.
That is why Cloud Solutions and Network Solutions should be designed as part of the wider resilience architecture. Connectivity, identity, endpoints, data and applications all form part of the recovery chain.
Dynamics 365 Jump Start: accelerate carefully
A Dynamics 365 Jump Start should not mean rushing into configuration before the business understands what it is trying to improve.
A well-structured implementation support programme can provide an accelerated but controlled route through:
- Discovery – documenting current processes, pain points and data dependencies.
- Prioritisation – selecting the first business area where improvement will create measurable value.
- Target design – deciding which processes belong in Dynamics 365 and which require integration or redesign.
- Data preparation – identifying duplication, incomplete records and retention requirements.
- Security design – defining roles, permissions, authentication and separation of duties.
- Integration planning – connecting the new platform to legacy systems, banking, logistics or specialist applications.
- User adoption – preparing people for new workflows rather than simply issuing new logins.
- Cutover and support – planning the transition, monitoring results and resolving issues quickly.
The best Dynamics 365 implementation support is not driven by software features. It is driven by the operating model the business needs.
Where IBM i remains in place, the programme may use a staged coexistence model. Data and processes can move in controlled domains, while the established platform continues to support functions that are not yet ready for replacement.
That approach reduces operational risk and gives the organisation time to validate results before retiring anything important.
Technology Expense Management turns modernisation into an investment case
Cloud migration can improve flexibility, but it does not automatically reduce cost. Without governance, organisations can end up paying for legacy support, new subscriptions, duplicated tools, unused licences and unnecessary infrastructure at the same time.
This is where Technology Expense Management becomes a strategic discipline rather than a procurement exercise.
A proper Technology Expense Management review should consider:
- Software and cloud licences against actual usage
- Duplicate applications serving similar purposes
- Support contracts and renewal dates
- Hardware replacement cycles
- Connectivity and telephony costs
- Hosting, backup and storage consumption
- The cost of maintaining systems that are being phased out
- Internal support time and operational inefficiency
The aim is not simply to cut expenditure. It is to redirect it towards services that improve resilience, productivity and control.
For example, reducing unused licences may fund stronger identity protection. Consolidating connectivity may support a better recovery design. Retiring obsolete infrastructure may offset the cost of a properly governed cloud platform.
This is cost rationalisation with a business case behind it.
The execution layer still matters
Strategy without execution is a well-formatted document. Once the target architecture and priorities are agreed, practical services are needed to keep the estate functioning.
These are important, but they should remain aligned to the overarching plan:
- Managed IT Services to monitor systems and maintain standards
- Helpdesk Support to resolve user issues and identify recurring problems
- Voice and Connectivity to support reliable communications
- Network Solutions to connect users, sites and cloud services securely
- Cloud management, endpoint protection, backup and infrastructure support
These are execution services, not substitutes for direction. A responsive helpdesk cannot compensate for a poorly designed access model. A fast network cannot fix an unclear recovery plan. A new ERP cannot resolve processes that were never properly understood.
Delivery may be supported by trusted specialist channel partners where particular skills or scale are required. The consultancy’s responsibility is to maintain architectural coherence, commercial discipline and accountability for the outcome.
A practical roadmap for UK SMEs
A resilient transition from IBM i Management to a modern Dynamics 365 estate can begin with five steps:
-
Baseline the current environment
Document systems, data, suppliers, costs, risks and dependencies. -
Set the compliance direction
Use Cyber Essentials as a practical baseline and assess whether ISO 27001 alignment or certification is appropriate. -
Define continuity requirements
Agree recovery priorities, recovery time objectives, recovery point objectives and testing responsibilities. -
Run a focused Dynamics 365 Jump Start
Start with a clearly defined business domain and measurable outcomes rather than attempting a total transformation at once. -
Introduce Technology Expense Management
Establish ongoing visibility of licences, contracts, infrastructure and usage before committing to further investment.
The result should be an IT estate that is easier to understand, easier to recover and easier to justify financially.
