Cloud Migration Services
Assess applications, dependencies and data before moving them. Plan a staged migration with agreed testing, cutover windows, rollback and support after go-live.
What a business cloud migration should include
Cloud migration services help a business assess and move applications, infrastructure or data to a new hosting environment. Start by agreeing the scope: what moves, what stays, which suppliers are involved and who signs off the result. UK businesses may need to check application licensing, data locations, support access and customer obligations alongside the technical plan.
A migration plan should include discovery, workload and dependency mapping, target design, a pilot, data transfer, acceptance testing, cutover and handover. Set an owner and acceptance criteria for each stage. Agree how users will access services, what backups protect the move and what triggers a rollback before the production cutover begins.
The work that determines whether a migration goes well happens before anything moves. It is an inventory: what is actually running, what depends on what, who uses it and when, and which of it nobody has touched in three years. That last category is usually larger than expected, and deciding to decommission rather than migrate is the cheapest decision available in the whole project.
The order matters as much as the plan. Moving the least critical workload first is how you find out whether your assumptions about performance, licensing and access hold, at a point where being wrong costs very little. Migrating the system the business cannot trade without on the first weekend is the pattern that produces the stories, and it is entirely avoidable.
Downtime and delivery time depend on the application, data volume, transfer method, supplier dependencies and testing results. Some workloads may support parallel running; others require an agreed outage. Compare proposals on migration effort, licences, data transfer, ongoing hosting, backup, support and exit arrangements rather than assuming the new monthly bill is the entire cost.
After go-live, test access, performance, backup and recovery against the agreed criteria. Confirm documentation, administrator access, monitoring and support ownership before decommissioning the old environment. A completed transfer is not the same as an accepted and supported service.
Why Migrate with SCG?
Expert Planning
Every migration starts with a thorough assessment of your current environment, dependencies and goals — so we build the right roadmap from the outset.
Planned Cutover
Agree testing, any outage window and rollback criteria around each workload. Service continuity depends on the migration design and application.
Managed Migration
From initial assessment through to go-live and beyond, our team manages the entire migration process — so you can focus on running your business.
Who we work with
We are independent of any single network or vendor, so the recommendation follows the requirement.

Cloud Migration Services — Common Questions
Will my business go offline during migration?
An outage may be needed for some workloads. The assessment should establish whether parallel running or staged transfer is possible and define any cutover window, acceptance tests and rollback conditions. Do not assume that every application can move without downtime.
Can you migrate just one application?
Yes, and it is frequently the right way to start. Scoping to a single application lets you test the assumptions about performance, licensing and access at a point where being wrong is cheap, and it produces a realistic timescale for the rest. Migrating everything at once is possible but it removes the opportunity to learn anything before the expensive part.
What should move to the cloud first?
Start with what is cheapest to move and most painful to keep: file storage, email, backup and test environments. Leave anything with hard compliance, latency or licensing constraints until the assessment says how to handle it — that is what the initial audit is for.
How much does a cloud migration cost?
The scope, application dependencies, data volume, licensing, transfer requirements and testing determine the project cost. Request a scoped proposal separating one-off migration work from recurring hosting, connectivity, backup and support. A fixed price or timeline cannot be inferred from the number of users alone.
Can some applications stay on-site?
Yes. Assess each workload before deciding whether to move, retain, replace or retire it. If private or on-site systems need to connect to public cloud services, consider a hybrid design and document connectivity, access controls and support responsibilities for both environments.
Who supports the environment after the move?
Agree that before the cutover. The handover should identify who owns monitoring, identities, updates, user support, backups and incidents, with acceptance tests and escalation routes. Ongoing managed IT support should be explicitly scoped rather than assumed to be included in project delivery.
Plan your next step
Compare related options, check what needs to work together and prepare the details for a useful conversation.
- Compare hybrid cloud deployment options →Decide which workloads should move, remain on-site or be replaced before committing to a migration.
- Plan support after the cloud migration →Connect technical handover to ongoing monitoring, user support, backup and recovery ownership.
- Discuss a scoped cloud migration →Bring the applications, users, data, locations and business deadlines that the migration needs to support.
