Cloud Migration Checklist for Indian SMEs

Many small and mid-sized businesses in Mumbai, Thane and Pune still run accounting, ERP and file servers on a machine in the office cupboard. When that server ages out, the natural question is whether to buy new hardware or move to the cloud. A cloud migration checklist helps answer that question honestly and, if you do move, keeps the project from turning into weeks of downtime and surprise bills.

The problems we see most often are not technical. They are unclear goals, an incomplete list of what is running, licences that do not transfer, and monthly cloud costs nobody estimated properly. This checklist is written for SME owners, finance heads and IT managers who want a practical, step-by-step plan.

Step 1: Be Clear About Why You Are Moving

Write down the two or three outcomes that matter most. Common reasons include:

• Avoiding a large hardware refresh and the cost of maintaining an on-premise server.
• Giving staff at multiple branches or working from home secure access to the same systems.
• Improving backup and disaster recovery after a hardware failure, flood or ransomware scare.
• Scaling capacity quickly for seasonal peaks, such as year-end closing or festive sales.

These goals decide what to move first and how to measure success. If cost reduction is the only goal, check the numbers carefully, because cloud can cost more than a well-used local server if it is not managed.

Also name one person who owns the project on the business side. This is usually the finance head or operations head, not only the IT person. They approve downtime windows, settle priorities between departments and sign off each phase.

Step 2: Start Your Cloud Migration Checklist With an Inventory

You cannot migrate what you do not know about. List every system and dependency:

• Applications: ERP, accounting software, CRM, HRMS, custom apps, email and file shares.
• Servers and storage: operating system versions, CPU, memory, disk usage and growth trends.
• Databases: type, version, size and which applications depend on them.
• Integrations: connections to banks, GST software, payment gateways, biometric devices, printers and barcode scanners.
• Licences: whether each software licence allows cloud hosting, and on what terms.
• Users and access: who uses what, from where and at which times.

Pay special attention to legacy software tied to a USB dongle, a specific machine or a local printer. These often need a different approach.

Step 3: Choose a Migration Approach for Each Workload

Not everything should move the same way. For each application, pick one of these common strategies:

1. Rehost (lift and shift): move the server as it is to a cloud virtual machine. Fastest, but it carries over existing inefficiencies.
2. Replatform: make small changes, such as moving a database to a managed database service.
3. Refactor: redesign the application to use cloud-native services. Most effort, most long-term benefit.
4. Repurchase: replace the application with a SaaS product, for example moving from a self-hosted mail server to a hosted email service.
5. Retire: switch off applications nobody uses.
6. Retain: keep some systems on-premise for now, for reasons of cost, latency or dependency on local hardware.

For most SMEs, a mix of rehost, repurchase and retire covers the first phase. Refactoring can come later once the basics are stable.

Step 4: Plan Security, Compliance and Data Location

Moving to the cloud shares security responsibility between you and the provider. The provider secures the underlying infrastructure. You remain responsible for user access, configuration, data and applications.

• Identity: enforce multi-factor authentication for all admin accounts and, ideally, all users.
• Network: restrict access with firewalls, security groups and VPN or private connectivity. Never expose remote desktop or database ports directly to the internet.
• Encryption: encrypt data at rest and in transit.
• Logging: turn on audit logs and keep them. CERT-In directions issued in 2022 require reporting of specified cyber incidents within six hours and retention of certain logs, so good logging matters for compliance as well as security.
• Personal data: the Digital Personal Data Protection Act, 2023 applies to businesses that process personal data of customers and employees. Map where such data will sit and who can access it. The detailed rules under the Act are yet to be notified, so plan for consent, security safeguards and breach handling in a way that can adapt.
• Data location: choose a region in India if your customers, contracts or sector rules require it. Several major providers operate data centre regions in Mumbai. If you supply to government departments, check whether they require a cloud service provider empanelled by MeitY.

Step 5: Estimate Costs Realistically

Cloud pricing is flexible but easy to underestimate. Include:

• Compute, storage and database charges, sized from your actual usage rather than the old server's specifications.
• Data transfer charges, especially for large backups or heavy downloads.
• Backup, disaster recovery and monitoring tools.
• Software licences, which can change when you move to the cloud.
• Internet bandwidth upgrades at your offices.
• Migration effort and ongoing management.

Compare this with the full cost of staying on-premise over three to five years: hardware, power, UPS, cooling, AMC and staff time. Then add controls from day one: budgets, alerts and a monthly review to shut down unused resources. An enterprise advisory review at this stage can prevent expensive decisions that are hard to reverse.

Step 6: Test, Cut Over and Stabilise

The migration itself should be boring. Plan it that way:

1. Pilot first: move a low-risk workload, such as a file share, and learn from it.
2. Take verified backups of everything before each move, and test that you can restore them.
3. Test with real users: ask the accounts and operations teams to run their daily tasks in the new environment before cut-over.
4. Schedule cut-over for a low-activity window, such as a weekend outside month-end or GST filing dates.
5. Keep a rollback plan and leave the old server running, read-only, for a few weeks.
6. Stabilise: monitor performance, right-size servers after a month of real usage and document the new setup.

Keep your cloud migration checklist as a living document after go-live. Update it with what went well and what did not, so the next workload moves faster and with fewer surprises.

Frequently Asked Questions

How long does cloud migration take for an SME?

It depends on the number of applications and their complexity. Simple file and email moves may take days. ERP and custom applications usually need several weeks, including testing.

Is cloud cheaper than an on-premise server?

Not always. Cloud avoids hardware purchases and improves resilience, but running costs need active management. Compare total costs over three to five years before deciding.

Can Tally or other accounting software run on the cloud?

Many accounting applications can run on a cloud server with remote access. Check the vendor's licensing terms for cloud or multi-user hosting first.

What is the most common cloud migration mistake?

Skipping the inventory. Forgotten integrations, licences and devices cause most delays and failures after cut-over.
