On-Premise to Cloud Migration for UK SMEs

Move your servers, files and applications to Azure with a clear cost breakdown, no downtime surprises, and 24/7 monitoring once you're live.

Clear Cost Planning

You'll know your Azure migration cost upfront, with no vague estimates that turn into surprise invoices halfway through the project.

Minimal Disruption

Migrations are planned and phased around your business hours, so staff keep working while servers move in the background.

Supported After Go-Live

24/7 monitoring and managed IT support continue after migration, so your new Azure environment is looked after, not left to run itself.

On-premise to cloud migration without the guesswork

Most UK SMEs still running on-premise servers didn't choose to stay there out of loyalty to the hardware — it's usually a mix of not having the time to plan a migration properly, uncertainty about what it will actually cost, and a healthy fear of downtime during the switch. Those concerns are reasonable. A poorly planned on-premise to Azure migration can genuinely disrupt a business for days. A properly planned one, by contrast, is largely invisible to your staff, who simply notice that things feel a bit faster and that IT stops raising the same recurring hardware problems.

We plan every on-premise server migration around your specific applications, data volumes and usage patterns, rather than a generic lift-and-shift template. Some workloads move cleanly to Azure with minimal changes; others need reconfiguring first, and knowing the difference before you start is what keeps a migration on budget and on schedule. We map out dependencies between servers and applications early, so nothing gets moved in an order that breaks something else further down the chain. This matters more than it might sound — many SME environments have grown organically over years, with a file server, an ageing line-of-business application and a handful of network shares all quietly depending on each other in ways nobody has fully documented, and untangling those dependencies properly before moving anything is what separates a smooth migration from one that surfaces unpleasant surprises midway through.

Cost is usually the first question, and rightly so — an on-premise to Azure migration cost varies significantly depending on the number of servers, the volume of data, and whether applications need re-architecting or can be moved largely as-is. We provide a clear breakdown before any work begins, covering both the one-off migration cost and what ongoing Azure hosting is likely to cost month to month, so you can compare it honestly against the ageing hardware, maintenance contracts and eventual replacement cost of staying on-premise.

It's also worth being honest about what a migration doesn't fix on its own. Moving a poorly performing application to Azure without addressing why it performs poorly usually just relocates the problem to a new environment. Part of our audit process is identifying which issues are genuinely infrastructure-related and will improve with the move, and which are application or configuration issues that need separate attention — so you go into the project with realistic expectations about what changes and what doesn't. We'd rather flag that upfront than let you discover it after the fact, when it's harder to tell whether "the cloud didn't help" or the underlying application simply still needs attention.

What on-premise to cloud migration involves

A migration typically starts with a full audit of your current environment: what servers exist, what's running on them, how much data needs to move, and which applications have dependencies on specific hardware or software versions. From there we design the target Azure environment, sized appropriately rather than oversized, and plan the migration sequence to minimise disruption. Data and applications are then moved in phases, tested at each stage, before we formally decommission the old on-premise infrastructure once everything is confirmed working. Decommissioning itself is handled carefully too — old servers often need secure data wiping before disposal or resale, and any remaining warranty or leasing arrangements need closing out properly rather than left as loose ends.

Delivered UK-Wide, Remote-First

We deliver on-premise server migration services UK-wide, working remotely from our base in the City of London, with on-site support available in London for any physical hardware decommissioning that needs hands-on attention.

Supported Long After Go-Live

Once your migration is complete, 24/7 monitoring and managed IT support continue as standard, backed by our 99% SLA guarantee, so your new Azure environment stays reliable long after the project itself has finished.

UK businesses look at cloud migration when

Ageing on-premise servers are approaching end of life or becoming expensive to maintain
Remote and hybrid working is limiting what staff can access reliably from home
Nobody has a clear picture of what an Azure migration would actually cost
Server outages or slow performance are affecting day-to-day productivity
Backup and disaster recovery on the current setup feel like an afterthought rather than a plan
The business is growing and on-premise capacity can't scale without another hardware purchase
A previous attempt at migration was scoped badly and never actually happened
Cyber Essentials certification requirements are exposing gaps in current server security
They want a single provider to manage the migration and the ongoing IT support afterwards

Why choose Cloudswitched for your cloud migration?

We plan every on-premise to cloud migration around your actual applications and data, not a generic lift-and-shift checklist, so the Azure environment you end up with is sized and configured for how your business really works.

Cost is never a mystery. You'll see a clear breakdown of migration cost and expected ongoing Azure hosting cost before any work begins, so you can compare it honestly against staying on-premise.

Migrations are phased and tested at every stage to minimise disruption, and we schedule the more disruptive steps outside core business hours wherever possible.

We don't disappear once the migration is done. 24/7 monitoring, managed IT support and cloud backup continue as standard afterwards, backed by our 99% SLA guarantee, so the new environment stays reliable.

We deliver UK-wide, remotely, from our base in the City of London, with on-site support available in London for any hardware decommissioning that genuinely needs hands-on attention.

Where a client's existing infrastructure is a genuinely awkward mix of legacy applications, custom scripts and hardware nobody fully documented, we take the time to understand it properly before quoting, rather than promising a fast, simple migration that turns into a drawn-out, over-budget project once the real complexity surfaces.

We also think beyond the migration itself to how your business will actually operate afterwards. That includes making sure staff know what, if anything, changes for them day to day, checking that remote and hybrid workers can access everything they need from an Azure-hosted environment just as reliably as they could in the office, and confirming that cloud backup and disaster recovery are properly configured from the very first day of go-live rather than added as a follow-up project weeks later.

On-premise to cloud migration for UK businesses

On-premise versus Azure cloud servers

01

On-Premise Servers

Capital cost upfront for hardware, ongoing maintenance and replacement cycles, and a fixed capacity that requires another purchase to scale.

02

Basic Cloud Hosting

Lower upfront cost than on-premise, but without proper configuration and monitoring, performance and security can be inconsistent.

03

Managed Azure Migration

Properly sized, monitored and supported Azure environment, with predictable ongoing costs and capacity that scales as the business grows.

Cloud Migration Support Across the UK

We deliver on-premise to cloud migration and on-premise server migration UK-wide, remotely, from our base in the City of London, with on-site support available in London for physical hardware decommissioning. Whether you're a single-server business or run infrastructure across several sites, the same principles apply: audit thoroughly, plan for minimal disruption, and support the environment properly once it's live.

Signs your business is ready for cloud migration

A handful of situations come up repeatedly when businesses first contact us about moving off on-premise infrastructure. Sometimes it's a server nearing the end of its warranty with no clear replacement plan in place. Sometimes it's a growing remote or hybrid workforce that on-premise infrastructure was never really designed to support well. And increasingly, it's a straightforward cost comparison — once you factor in hardware replacement, maintenance contracts and the staff time spent firefighting ageing servers, a properly costed Azure migration often works out more predictable than continuing to patch an on-premise environment that's quietly becoming a liability.

Common concerns about moving away from on-premise servers

Two worries come up in almost every migration conversation we have. The first is cost — business owners have often heard vague stories about cloud projects running over budget, and want a genuine, itemised figure rather than a rough estimate. The second is disruption — nobody wants a migration that takes the business offline during a busy trading period. We address both directly: a clear cost breakdown before work begins, and a phased migration plan that's tested at each stage and scheduled to keep any unavoidable downtime as short and predictable as possible.

Questions to ask before starting a cloud migration

Ask for a proper breakdown of both the one-off migration cost and the expected ongoing Azure hosting cost, so you're comparing like for like against your current on-premise setup rather than just the headline migration fee.

Downtime planning: ask specifically how disruption will be minimised, and whether more disruptive steps can be scheduled outside core business hours.

Getting started: a free consultation and infrastructure audit is the right first step, so you understand the real scope and cost before committing to a project.

Support after go-live: confirm what happens once the migration is complete — ongoing monitoring, backup and support should be part of the conversation from day one, not an afterthought.

Data volume and sensitivity: be upfront about how much data you're moving and whether any of it is subject to specific regulatory or contractual requirements, as this can affect both timeline and how the migration is sequenced.

Frequently Asked Questions

Got questions about on-premise to cloud migration? We've answered the most common ones below. If you need more detail, get in touch.

What does an on-premise to Azure migration cost?

It depends on the number of servers, data volume and application complexity involved. We provide a clear cost breakdown covering both the one-off migration and expected ongoing Azure hosting cost after a full infrastructure audit, with no vague estimates.

How long does an on-premise server migration take?

Timescales vary with complexity, but most SME migrations run over several weeks, phased to minimise disruption. We provide a realistic timeline as part of the initial audit rather than an optimistic estimate that slips later.

Will there be downtime during migration?

We plan migrations in phases and schedule the more disruptive steps outside core business hours wherever possible, so disruption is minimised. Some short cutover windows are usually unavoidable, but they're planned and communicated in advance.

Do I need to replace my on-premise hardware first?

No, migration typically replaces the need for further on-premise hardware investment. We assess your current setup and plan the move to Azure so you avoid another hardware purchase cycle.

Is Azure cheaper than running on-premise servers?

It depends on your current infrastructure age and usage, but Azure typically removes large upfront hardware costs in favour of predictable ongoing hosting costs. We provide an honest cost comparison based on your specific environment.

What happens to our data during migration?

Data is migrated in tested phases with verification at each stage, and cloud backup is in place from the point systems go live, so data integrity is protected throughout the process.

Can you support us after the migration is complete?

Yes, 24/7 monitoring and managed IT support continue as standard once you're live on Azure, backed by our 99% SLA guarantee, so the same team that migrated you keeps looking after the environment.

Do you support businesses across the whole UK?

Yes, we deliver on-premise to cloud migration UK-wide, remotely, from our base in the City of London, with on-site support available in London for physical hardware decommissioning.
