How to Move Your Business to the Cloud in 5 Steps
Moving your business to the cloud is one of the most impactful technology decisions you can make. Cloud infrastructure reduces hardware costs, enables secure remote working, improves disaster recovery, and scales with your business. But without a clear plan, migrations can cause downtime, data loss, or unexpected costs. This five-step guide walks you through the entire process in plain English.
Step 1 — Assess Your Current Infrastructure
Before migrating anything, catalogue what you currently have: servers, applications, databases, file shares, and the users who depend on each one. Identify which workloads are business-critical (cannot afford downtime), which are suitable for direct lift-and-shift (move as-is), and which should be refactored for cloud-native services. At this stage, also assess your current internet bandwidth — cloud working requires a reliable, fast connection. If your connectivity is poor, upgrading it is part of the migration project.
Step 2 — Choose the Right Cloud Platform
For most UK SMEs, the decision comes down to Microsoft 365 (for productivity and collaboration), Microsoft Azure (for infrastructure and custom apps), or a combination of both. Microsoft 365 is almost always the right starting point — it replaces on-premises Exchange and file servers with Teams, SharePoint, and OneDrive at a predictable per-user monthly cost. Azure is better suited to businesses running bespoke line-of-business applications, databases, or virtual desktops. Google Workspace is a viable alternative to Microsoft 365 for businesses without a heavy Microsoft dependency.
Step 3 — Migrate Data and Applications in Phases
Never migrate everything at once. Start with low-risk workloads — shared drives, email, or collaboration tools — so your team can get comfortable with the new environment before critical systems move. Use a pilot group of 5–10 users to iron out issues before a company-wide rollout. For data migration, use Microsoft's own migration tooling (SharePoint Migration Tool, IMAP migration for email) or partner with an accredited Microsoft CSP like AARAi Solutions to ensure data integrity. Always verify that backups are in place before starting any migration activity.
Step 4 — Secure Your Cloud Environment
Cloud security is a shared responsibility — your provider secures the infrastructure, but you are responsible for configuring it correctly. Enable Multi-Factor Authentication (MFA) for all users immediately — this single step prevents over 99% of account compromise attacks. Configure Conditional Access policies to block sign-ins from unexpected locations. Implement Microsoft Defender for Business (included in Microsoft 365 Business Premium) for endpoint protection. Set up data loss prevention (DLP) policies to prevent sensitive information leaving your organisation. Finally, run regular security reviews — ideally quarterly.
Frequently Asked Questions
How long does a cloud migration take for a small business?▾
For a business of 10–50 users migrating to Microsoft 365, the core migration (email, files, Teams setup) typically takes 2–6 weeks depending on data volume and complexity. Larger or more complex migrations can take 3–6 months.
Will my staff experience downtime during the migration?▾
A well-planned migration minimises disruption. Email migrations are usually done with zero downtime using a cutover or staged approach. File migrations can be scheduled outside business hours. A good migration partner will produce a detailed cutover plan in advance.
How much does cloud migration cost in the UK?▾
Microsoft 365 Business Basic starts at £4.90 per user/month; Business Standard is £9.40/user/month. Professional migration services typically cost £500–£5,000 for an SME depending on complexity. The ongoing savings from eliminating on-premises hardware usually offset migration costs within 12–18 months.
Is the cloud secure enough for sensitive business data?▾
Yes — when configured correctly. Microsoft Azure and Microsoft 365 hold ISO 27001, SOC 2, and Cyber Essentials certifications. The key is correct configuration: MFA enabled, Conditional Access policies set, and regular security reviews conducted.
Does AARAi Solutions handle Microsoft 365 migrations?▾
Yes. AARAi Solutions is a Microsoft Cloud Solution Provider (CSP) and manages end-to-end Microsoft 365 and Azure migrations for UK SMEs, including pre-migration assessment, data migration, security configuration, and staff training.
