From On-Prem to cloud: a four-step migration playbook for SMEs

Table of Contents

Cloud migration does not have to be risky, costly, or disruptive. With the right plan, small and medium businesses can move from on-premises servers to the cloud with predictable spend, stronger security, and better disaster recovery. The key is a staged approach that respects your current environment and business priorities.

This playbook outlines Screwloose IT’s consultation → discovery → proposal → migration framework. It covers readiness, cost modelling, identity and security, data migration, change management, and how to phase cutovers to minimise downtime. It also includes typical timelines for common workloads and what to watch out for along the way, with a focus on Australian data residency and month-to-month flexibility.

Why migrate: cost, risk, and flexibility

Moving to cloud typically reduces cost and risk for SMEs because you trade capital expenses for predictable operating costs, avoid surprise hardware failures, and right-size capacity on demand. You also gain faster recovery options, stronger identity controls, and continuous patching of underlying infrastructure.

  • Cost: You stop overbuying server capacity for peak loads and pay for what you use. You also avoid big refresh cycles and support contracts on aging hardware.
  • Risk: Cloud platforms and managed controls reduce single points of failure, improve backup reliability, and support geo-resiliency. With MFA and least-privilege access, credential risk drops significantly.
  • Flexibility: Month-to-month services let you scale with headcount and projects without lock-in, which aligns spend to actual business need.

Step 1: Consultation and readiness assessment

A short consultation sets scope and goals. From there, a structured readiness assessment maps your environment and constraints:

  • Inventory: Servers, storage, line-of-business apps, databases, identities, shared files, and email.
  • Integrations and latency: Which systems talk to each other, and what must stay close to users or devices.
  • Security posture: MFA coverage, admin privileges, patch status, endpoint protection, and backup maturity.
  • Compliance and residency: Where data must reside. Screwloose IT prioritises Australian data residency for sovereignty and latency.
  • User impact: Key workflows, branch offices, mobile users, and training needs.

Outputs include a baseline architecture, risk register, and a feasibility view of what should move first. Some legacy or latency-sensitive workloads may stay on-premises, while most email, files, and modern apps are strong candidates for cloud.

Step 2: Discovery and cost modelling

Discovery deepens the technical detail and aligns costs with outcomes. The focus is to right-size and avoid bill shock.

  • Performance profiling: Actual CPU, memory, storage, and IOPS patterns inform the target sizes for virtual machines and storage tiers.
  • Licensing review: Map current licenses to cloud equivalents or bundled plans (for example, Microsoft 365) to remove duplication.
  • Identity strategy: Decide on Azure AD-led authentication, hybrid join, Conditional Access, and MFA with Duo.
  • Backup and DR targets: Agree on Recovery Time Objective (RTO) and Recovery Point Objective (RPO) and select backup tools that provide immutable copies and routine test restores.
  • Financials: Compare a three-year on-premises refresh against a month-to-month cloud plan with Australian-region services. Include migration effort, backup, security tools, and ongoing management.

The result is a transparent cost model with options that suit your risk tolerance. Month-to-month arrangements let you scale up or down without lock-in.

Step 3: Proposal and migration plan

The proposal consolidates design decisions and sequences the move with minimal downtime.

  • Architecture: Target cloud services, identity, networking, backup, and security controls.
  • Security baseline: MFA via Duo, least-privilege admin roles, hardening standards, and email and endpoint protections aligned to the Essential Eight.
  • Data protection: Multi-layer backup with documented test-restores and clear RTO/RPO.
  • Cutover strategy: Phased, workload-by-workload migrations with backout plans and business-aligned change windows.
  • Change management: Communication, pilot groups, training, and support arrangements after go-live.

Timelines typically look like this:

  • Email (Microsoft 365 or similar): 1 to 2 weeks for small teams, 2 to 4 weeks for multi-site businesses including coexistence and staged mailbox moves.
  • Files and collaboration (SharePoint, OneDrive, or cloud file services): 2 to 4 weeks, including permissions mapping, pilot testing, and migration waves.
  • Line-of-business apps: 4 to 8 weeks depending on complexity, database size, vendor support, and integration testing. Some may be rehosted to virtual machines, some replatformed to managed databases, others retained on-premises short term.

Step 4: Migration and cutover with low downtime

Successful cutovers rely on rehearsal and clear checkpoints.

  • Pilot first: Move a small group to validate performance, permissions, and workflows.
  • Sync and swing: Pre-seed data to cloud, then perform a short delta sync during the cutover window. For email, use staged or hybrid migration so users remain productive.
  • Identity-first: Enable Duo MFA and Conditional Access early so accounts are protected before data moves. Phase enforcement to avoid lockouts.
  • Validate and support: Post-cutover checks confirm access, printing, scanning, and integrations. Provide floor-walking or quick-start guides for users.

For file servers, a weekend or evening final sync often achieves near-zero disruption. For apps, schedule brief maintenance windows with a tested rollback plan.

Security, identity, and compliance foundations

Security is not an afterthought. It is built into each phase.

  • MFA with Duo: Fast, user-friendly multi-factor authentication for admins and all remote access.
  • Least-privilege and role-based access: Reduce standing admin rights and use just-in-time elevation where possible.
  • Patch and protect: Enforce patch baselines and endpoint protection, including email threat filtering.
  • Backups with proof: Immutable cloud copies, MFA on backup consoles, and regular test restores documented against agreed RTO/RPO.
  • Residency: Host sensitive workloads and backups in Australian regions to meet sovereignty and latency needs.

If you need ongoing help operating the environment, a managed IT services provider can take care of monitoring, patching, backups, and response so your team stays focused on the business.

Change management that users actually appreciate

Good change management lowers resistance and reduces tickets.

  • Communicate what is changing, why it matters, and when to expect it.
  • Use pilot groups to shape training materials and FAQs.
  • Provide concise how-to guides and short videos for new tools like OneDrive or Teams.
  • Staff extra support during the first week after each cutover wave.

Common pitfalls to avoid

  • Lifting and shifting everything: Rehost only what makes sense. Replatform or retire where possible.
  • Ignoring identity: Skipping MFA or delaying Conditional Access increases risk during transition.
  • Underestimating data clean-up: Migrating stale or duplicate data slows timelines and increases cost. Archive first.
  • No rollback plan: Always have a tested backout path and snapshots before cutover.
  • Forgetting printers and scanners: Test line-of-business peripherals and workflows end to end.
