Windows 11 Migration for Business UK: Planning, Costs & Timeline

Last updated: March 2026  |  Reviewed by: Connection Technologies team

Migration Timeline

Here is a step-by-step guide to the typical process:

Step 1: Discovery and audit — your provider should conduct a thorough audit of your current setup, including infrastructure, software, security posture and pain points. This typically takes 1–2 weeks and should be free of charge.

Step 2: Solution design — based on the audit, your provider designs a solution tailored to your business needs, size and budget. This should include a detailed service specification, pricing breakdown and implementation timeline.

Step 3: Agreement and planning — once you approve the solution, your provider creates a detailed implementation plan with milestones, responsibilities and a communication schedule. This is also when contracts are signed.

Step 4: Implementation — the actual migration or setup, typically conducted in phases to minimise disruption. Critical systems are migrated during off-peak hours, and your provider should have a rollback plan for every change.

Step 5: Testing and handover — thorough testing of all systems before going live, followed by user training and documentation. Your provider should be available for intensive support during the first 2–4 weeks.

Step 6: Ongoing management — regular service reviews (monthly or quarterly), proactive monitoring, continuous improvement and strategic planning. This is where the real value of a managed service becomes apparent.

Connection Technologies follows this exact process for every new client, with a named project manager overseeing the transition and a named account manager for ongoing support.

Hardware Compatibility Check

Cloud and infrastructure decisions have a direct impact on business performance, security and costs. Getting them right from the start saves significant time and money compared to fixing problems later.

The UK market offers a wide range of options, from public cloud platforms (Azure, AWS, Google Cloud) to managed hosting, colocation and hybrid solutions. The right choice depends on your workloads, compliance requirements, budget and in-house expertise. Most UK SMEs are best served by a combination of Microsoft 365 for productivity, Azure for cloud infrastructure and a managed provider to handle the complexity.

One of the biggest mistakes UK businesses make is treating infrastructure decisions as purely technical. In reality, your choice of cloud platform, backup strategy, network design and security architecture has direct business implications — affecting uptime, productivity, compliance posture and total cost of ownership.

The PSTN switch-off in January 2027 is accelerating cloud adoption across the UK, as businesses must move their phone systems to internet-based alternatives. This creates an opportunity to rethink your entire infrastructure — not just phones, but connectivity, security and how your team accesses business applications.

Connection Technologies helps UK businesses design, implement and manage cloud and infrastructure solutions as part of unified managed IT services. We provide vendor-neutral advice (we are not locked into any single cloud platform) and ongoing management from £45/user/month, ensuring your infrastructure is reliable, secure and cost-effective.

Costs Breakdown

Pricing transparency is one of the most important factors when choosing any business technology provider. The quoted price should be the price you pay — no hidden fees, no mid-contract increases, no surprise charges.

In the UK telecoms and IT market, the most common pricing traps are: RPI-linked annual increases (adding 5–10% per year to your bill), out-of-bundle charges (international calls, roaming, premium numbers), setup fees that were not mentioned during the sales process, and early termination charges calculated as 100% of remaining contract value.

Connection Technologies quotes a fixed monthly price that does not change for the duration of your contract. No RPI increases, no hidden admin fees, no surprises. Every quote itemises exactly what you are paying for.

Frequently Asked Questions

What is the difference between public cloud and private cloud?

Public cloud (Azure, AWS, Google Cloud) shares infrastructure across multiple tenants and offers pay-as-you-go pricing. Private cloud dedicates infrastructure to your organisation, offering more control and potentially better compliance. Most UK SMEs use public cloud for cost efficiency.

How much does cloud hosting cost for a UK business?

Cloud hosting costs vary widely depending on workloads. A typical UK SME spends £500–£3,000/month on cloud infrastructure (compute, storage, networking). Managed cloud services add £10–£30/user/month for monitoring, optimisation and support.

Is my data safe in the cloud?

Yes, when properly configured. Major cloud platforms (Azure, AWS) invest billions in security and hold more certifications than most on-premise environments. The key is proper configuration — misconfigured cloud services are the number one cause of cloud data breaches.

Should I choose Azure or AWS?

For most UK businesses already using Microsoft 365, Azure is the natural choice due to seamless integration, familiar management tools and UK data centre locations. AWS is often better for developer-heavy organisations or those running Linux workloads.

What is SD-WAN and do I need it?

SD-WAN (Software-Defined Wide Area Network) optimises network traffic across multiple internet connections, improving performance and reliability for multi-site businesses. It is worth considering if you have 3+ sites or rely heavily on cloud applications.

How long does cloud migration take?

A typical cloud migration for a UK SME takes 4–12 weeks depending on complexity. Simple email and file migrations can be done in 1–2 weeks. Full infrastructure migrations (servers, applications, databases) take 8–12 weeks with proper planning.
