You’re staring at an Azure login screen wondering how you got here — maybe it’s the CFO who wants the on-prem server room retired, maybe it’s the size of your current cloud bill next to Azure’s Hybrid Benefit pitch. Whatever got you here, you have real questions, and this guide answers them straight: cost, timelines, tools, rollback risk, security, and whether Azure is actually the right fit for you. We support AWS, Azure, and Google Cloud, so every answer here is built to be honest, not to sell you Azure specifically.
Looking for the strategic framework behind how to migrate — the 6 R’s? Start with our 6 R’s of Cloud Migration guide, then come back here for the Azure-specific mechanics.
Basics & Planning
What is Azure cloud migration and how is it different from “cloud migration” in general?
Azure cloud migration means moving your servers, applications, and data specifically onto Microsoft’s Azure — not another platform like AWS or Google Cloud. The underlying process (assess what you have, plan the move, migrate it, optimize afterward) is largely the same no matter which cloud you pick.
What changes are the tools and licensing levers that only exist inside Azure: Azure Migrate for the actual move, Azure Hybrid Benefit for cutting licensing costs, and Entra ID for identity. Microsoft frames its migration guidance around something called the Cloud Adoption Framework (CAF) — worth knowing the name, because most Azure-specific advice you’ll run into is built on top of it.
What is Microsoft’s Cloud Adoption Framework, and do I need to follow all of it as a small business?
No. CAF is Microsoft’s structure for how organizations plan, execute, and govern a cloud move — four sequential phases (Strategy, Plan, Ready, Adopt) plus three disciplines that run continuously in the background (Govern, Secure, Manage). It’s a menu, not a mandate. A 15-server company doesn’t need the governance apparatus a 3,000-person enterprise does. Take the assessment and planning steps seriously; treat the governance tooling as something you scale up later, not something you need on day one.
What are the “6 R’s” (or 7 R’s) of cloud migration, and which one fits my application?
Rehost, Replatform, Refactor, Rebuild, Repurchase, Retire, Retain — strategies for what to do with each app you’re moving. Most SMBs start with Rehost — lift-and-shift, no code changes — for anything stable and low-complexity, and reserve Refactor or Rebuild for apps actively costing them money or blocking growth. We break down the full decision framework, plus a quick-reference table, in The 6 R’s of Cloud Migration — read that in full before you sort your app inventory.
| Strategy | Best for | Effort | When to choose it |
| Rehost | Stable, low-complexity apps | Low | Default starting point for most SMB migrations |
| Replatform | Apps needing minor optimization | Low–Medium | You want managed services without a rebuild |
| Refactor | Apps with real technical debt | Medium–High | The app is costing you money or blocking growth |
| Rebuild | Legacy apps past their useful life | High | Starting fresh is cheaper than fixing it |
| Repurchase | Apps with a good SaaS alternative | Low | A commercial product already does this better |
| Retire | Apps nobody actually uses | None | Discovery reveals it’s dead weight (often 20–30% of inventory) |
| Retain | Apps that can’t move yet | None | Compliance, contracts, or dependencies block the move |
What is an Azure landing zone, and does a small business actually need one before migrating?
A landing zone is the pre-configured foundation — networking, identity, governance policy — that your workloads land into once they hit Azure. Microsoft’s own guidance splits this into a simple, single-subscription setup and a full enterprise-scale architecture. If you’re a startup or SMB, you want the simple version. Be wary of anyone pitching the enterprise template on day one — you’d be paying for governance complexity you don’t need yet.
Do I need to rewrite my applications to move them to Azure?
For most SMBs, no. The first move is almost always Rehost — via Azure Migrate’s Server Migration tool, which handles agentless or agent-based moves of your existing VMs with zero code changes. Refactoring or rebuilding is a later, optional decision you make once you know which apps are actually worth the investment — not a prerequisite to get off your current servers.
Cost & Licensing
How much does it actually cost to migrate to Azure?
Startups and small businesses typically land in the $40,000–$100,000 range; mid-sized companies run $100,000–$300,000; enterprise migrations run $300,000–$600,000 and up. These are general cloud-migration benchmarks, not Azure-exclusive pricing — the real driver is your data volume, app count, and complexity, not the platform you pick.
| Cost component | Typical range |
| Assessment & planning | $5,000 – $30,000 |
| Licensing & tools | $10,000 – $50,000 |
| Infrastructure | $20,000 – $150,000+ |
| Labor | $15,000 – $200,000 |
Migration cost is one line item in a much bigger picture — if you’re building this into your overall tech spend, our guide on how to build an IT budget for startups walks through the full process.
What is Azure Hybrid Benefit, and how much can it actually save?
If you already own on-prem Windows Server or SQL Server licenses with active Software Assurance, Azure Hybrid Benefit lets you apply them toward your Azure costs instead of paying for licensing twice. Combined with Reserved VM Instances, it can cut Windows Server costs by up to 80% versus standard pay-as-you-go, up to 76% for Linux, and up to 29% for SQL Server versus other leading cloud providers. That eligibility requirement — existing licenses with active Software Assurance — is exactly why companies already running Microsoft 365 or Windows Server see the biggest savings on Azure specifically.
Is Azure Migrate really free? What happens after the free period ends?
Mostly, and this is one of the most common points of confusion. Server Assessment — the discovery and planning tool — is free indefinitely. Server Migration is free for 180 days per machine; after that, Azure charges roughly $25/month per instance that remains in active replication. Database Migration Service operates on a similar free structure (up to 183 days for online migrations).
Keep in mind that once a machine completes its migration, replication stops and standard Azure compute and storage rates apply. Build your migration timeline around that 180-day window so you don’t pay unnecessary replication fees.

What hidden or overlooked costs catch companies off guard during an Azure migration?
The line items nobody budgets for usually stack up quickly. Companies often run their old on-prem environment in parallel longer than planned, or delay right-sizing resources until months after go-live. Other hidden costs include late Hybrid Benefit claims, forgotten non-production environments racking up charges, and security tools added piecemeal after launch.
Run a cost-optimization review within 30–60 days of go-live — that window is when these costs are still cheap to fix. A lot of this overlaps with a broader problem we cover in how to cut SaaS app sprawl without hurting productivity: unused resources are cheap to spot early and expensive to ignore.
Are there free Azure credits available for startups?
Yes — Microsoft for Startups offers Azure credits through its Founders Hub program, with entry-level credits available to most qualifying startups and higher tiers for companies meeting specific funding or spend thresholds. It’s a real lever, not marketing fluff, but it’s eligibility-based — check your qualification before you build it into your budget.
Timeline & Process
What’s the difference between Azure Migrate and Azure Site Recovery?
Azure Migrate is the orchestration layer — discovery, dependency mapping, assessment, and the migration process itself. Azure Site Recovery is the replication engine underneath it, and it doesn’t retire once you’re done migrating — it keeps running afterward as your disaster-recovery tool. Think of Migrate as the move, and Site Recovery as the insurance policy that outlives it.
Can I roll back to my old servers if the Azure migration doesn’t go well?
Not after a final cutover — once your on-premises source machine is shut down, Azure Migrate does not support rolling back. That’s a real risk, and it’s exactly why Azure Migrate includes Test Migration: a feature that lets you validate a workload’s functionality on Azure as many times as you want, without touching the source machine, before you commit to the real cutover. Run the test migration. Don’t skip it to save a week.
Can I migrate to Azure without downtime?
For a lot of workloads, close to zero downtime is achievable through replication-based cutover. But for smaller teams without a fully redundant parallel environment, a scheduled cutover window is still the realistic default. Database migrations have a clear tradeoff: offline migration means downtime from the moment the move starts, while online migration limits it to the final cutover — but online migration requires a Premium-tier target instance. Know which tradeoff you’re making before you schedule the maintenance window.
Tools & Methods
How do I know if my applications are even compatible with Azure before I start?
Azure Migrate’s Server Assessment tool is free with no time limit and exists specifically to flag compatibility issues, map dependencies, and generate sizing recommendations before you commit to anything. If you’re running custom .NET applications, Microsoft also offers a dedicated App Code Assessment toolkit for code-level compatibility checks. Run the assessment before you promise anyone a migration date.
What is Azure Database Migration Service, and will it cause downtime for our SQL Server?
Database Migration Service (DMS) is separate from Azure Migrate — it’s purpose-built for moving databases, not VM-level infrastructure, and it supports SQL Server 2008 and later. Microsoft’s own guidance is to test an offline migration first, so you know exactly how much downtime you’re looking at before deciding whether the added complexity of an online migration is worth avoiding it.
Do I need Azure Virtual Desktop as part of a standard server/infrastructure migration?
No — these are usually two separate decisions. A backend server or infrastructure migration through Azure Migrate has nothing to do with whether you also want to move your team’s desktops to Azure Virtual Desktop (AVD). AVD becomes relevant when you’re specifically enabling remote work or retiring physical desktop hardware, not as a default step in every migration. Microsoft even maintains a separate Cloud Adoption Framework planning track just for AVD — a sign that Microsoft itself treats it as its own project.
Security & Risk
What are the most common security mistakes companies make after migrating to Azure?
The specific, checkable list: insecure default configurations on services like App Services and Cosmos DB, weak secrets management, IP allow-lists broader than they need to be, treating the subscription boundary as your only security boundary, underused Defender and Security Center alerts, stale DNS records that leave subdomains open to takeover, no process for tearing down unused assets, no tagging strategy, and shared admin accounts. None of these are exotic. All of them are avoidable with a post-migration security review — see our Cyber Security services if you want that review done for you, or read Zero-Trust Access Control: A Practical Guide for Startups if identity and access are the piece you want to lock down first.
Who’s responsible for security after we migrate — Microsoft or us?
Both, split by layer. Microsoft secures the underlying cloud infrastructure — physical datacenters, host OS, network fabric. You remain responsible for identity, data classification, access controls, and application-level configuration, and exactly where that line sits shifts depending on whether you’re using IaaS, PaaS, or SaaS. This isn’t a minor technicality: misconfiguration, not sophisticated attacks, is now the single largest breach vector — 14% of all global breaches in 2026, up from 9% in 2024. That’s a governance gap, not a technology gap, and it’s one you own.
Is Azure migration too risky for a small team without dedicated IT/DevOps staff?
It’s riskier without a plan — not without a title. The teams that struggle are the ones that skip a pilot or test migration before full cutover, underestimate how long data transfer actually takes on their bandwidth, and have no rollback plan (see the rollback question above). One founder described migrating a bootstrapped app serving 100,000 users on a $20/month budget to Azure as something they were genuinely terrified of. That fear is normal. The fix isn’t hiring a DevOps team before you start — it’s running the test migration, budgeting real time for data transfer, and having a managed IT partner in your corner if you don’t have the internal bandwidth.

Multi-Cloud & Platform Choice
Should a startup or SMB choose AWS, Azure, or Google Cloud?
Honestly — it depends on what you’re already running, not on which platform has the best marketing. Azure tends to fit companies already invested in Microsoft 365 or Windows Server, because of identity continuity and Hybrid Benefit eligibility. AWS often fits teams already in that ecosystem or who want the broadest service catalog. GCP tends to get picked for data, analytics, and AI-heavy workloads. We support all three and don’t hold an Azure-specific partner tier — which means we have no incentive to tell you Azure is the answer if it isn’t.
We already use Microsoft 365 — does that make Azure the obvious choice?
Usually, yes — but not automatically. The real continuity benefits are concrete: a shared identity plane through Entra ID, Hybrid Benefit eligibility if you have existing Windows Server or SQL Server licenses with Software Assurance, and admin tooling your team already knows. Hybrid Benefit specifically only applies if you’re already in the Microsoft licensing ecosystem — exactly why M365 shops see outsized savings on Azure. Still, evaluate your actual application needs case by case rather than assuming M365 today means Azure is right for every workload.
Can we run a multi-cloud setup instead of committing to just Azure?
Yes, and it’s increasingly a deliberate strategy rather than an accident — companies use it for risk management and negotiating leverage, not just because they ended up there by history. It comes with real added operational complexity and cost from managing more than one platform, so go in with eyes open. This is exactly the posture we support at Interlaced: AWS, Azure, and GCP, with no pressure to consolidate onto one platform just because it’s easier for us. See Managed Cloud for how we support multi-cloud environments.
Post-Migration
What should we do in the first 30–60 days after migrating to Azure?
Right-size anything you over-provisioned during the move — most teams do, out of caution. Decommission the parallel or test environments you spun up during migration and forgot about. Complete your Hybrid Benefit eligibility review if you skipped it pre-migration. And run a security baseline review before you consider the migration actually finished. Over-provisioning and forgotten test environments are specifically why the 30–60 day window matters — costs compound fast if nobody’s watching.
How do we stop Azure costs from spiraling out of control after migration?
Set budgets and alerts in Azure Cost Management from day one, not after the first surprising invoice. Build a real tagging strategy so you know which team or project owns which cost. Schedule recurring right-sizing reviews instead of a one-time check. This isn’t optional housekeeping — 84% of organizations cite managing cloud spend as their single biggest cloud challenge, ahead of security and skills gaps combined.
Does migrating to Azure automatically make us HIPAA or SOC 2 compliant?
No — and this is one of the most common, costly misconceptions we see. Microsoft offers a HIPAA Business Associate Agreement and maintains a documented HIPAA/HITECH compliance offering, which covers the underlying infrastructure. But configuring access controls, encryption, logging, and policy correctly is still on you. Compliance isn’t something you inherit from the platform — it’s something you build on top of it. If you need to be HIPAA or SOC 2 compliant, that work needs to be part of your migration plan, not an afterthought. See our Compliance services if you want that built in from the start, or read IT Compliance Automation: Walk Into Your SOC 2 Audit Already Ready if SOC 2 specifically is already on your roadmap.
Still Not Sure Where to Start?
Every question above has a version that’s specific to your stack, your budget, and your team’s bandwidth. If you’d rather talk it through with someone who supports AWS, Azure, and GCP without a horse in the race, talk to Interlaced about your migration. We’ll tell you honestly which platform fits — and what it’ll actually cost to get there.
