8 Cloud Migration Challenges and Their Solutions

The biggest cloud migration challenges are security and compliance, downtime, cost control, data transfer, application compatibility, skills gaps, weak planning and post-migration performance. Cost is the most common pain: in the Flexera State of the Cloud Report, 2025, 84% of organizations named managing cloud spend their top cloud challenge.

What does cloud migration involve, and why is it hard?

Cloud migration is the process of moving data, applications and workloads from on-premises servers or data centers to a cloud computing environment. Most organizations already use the cloud or are planning further moves, and the market keeps growing: Gartner forecasts infrastructure as a service spending to grow 29.3% in 2026 (Gartner, 2026). Cloud migration can be complex and needs meticulous planning, but for most organizations the benefits outweigh the headaches.

Organizations that move smoothly to the cloud gain lower operating overhead for hardware they no longer own, better scalability and agility, and faster access to new capabilities. A migration is also a physical project. Even when every server moves to the cloud, your offices still depend on local networks, circuits, firewalls and devices, which is why onsite IT network services belong in the plan. Here are eight common challenges of cloud migration and what you can do about each one.

1. How do you keep data secure and compliant during cloud migration?

Data security is a top concern during any large data transfer. During migration, companies move data hosted in on-premises data centers or applications to the cloud, and there is a window when data exists in two places, access rules are in flux and temporary connections are open. Mishandled, it can feel like the Wild West.

Organizations need to address regulatory compliance, block unauthorized access, encrypt data in transit and at rest, and configure the new environment correctly to avoid data leaks. Third parties add risk: the Verizon Data Breach Investigations Report, 2025 found third-party involvement in breaches doubled to 30%, and a migration usually brings in several new vendors at once.

Solution

Every change management plan should include robust security measures, and you should choose a cloud service provider whose data privacy and security commitments meet your requirements. Protect sensitive information during migration by:

• Classifying data first, so you know what is regulated and where it must live
• Encrypting data in transit and at rest, and testing that encryption works as expected
• Using least-privilege access for migration accounts and removing them when the work ends
• Reviewing cloud configurations against a baseline before go-live
• Working with your compliance team or a third-party specialist to confirm the plan meets your standards

2. How do you minimize downtime and protect business continuity?

Downtime is a significant challenge and is often what holds organizations back from migrating at all. The true cost of downtime is hard to overstate: in Uptime Institute’s 2026 outage analysis, 57% of respondents said their most recent major outage cost more than $100,000 (Uptime Institute, 2026). Still, a planned, controlled cutover is far less risky than an unplanned failure of aging on-premises equipment.

Solution

The best protection is continual, thorough testing before, during and after migration. Migrate in waves, starting with low-risk workloads, and schedule cutovers in low-usage windows with a written rollback plan. Many businesses also design for failover, so that if one environment fails, operations can shift to another. A hybrid cloud environment, which combines on-premises infrastructure with public or private cloud, lets you keep critical systems running locally while others move, and gives you a fallback during the transition.

Your IT team or third-party experts should test functionality in real time during the process and keep testing after migration. For offices, have someone available onsite during cutover windows to check local connectivity, printers and line-of-business devices that depend on the migrated systems.

3. How do you control cloud migration costs?

Cost management is one of the most common cloud migration challenges. Cloud adoption brings new tools and costs that organizations overlook: data transfer, staff training, third-party specialists, higher bandwidth at every office, running old and new environments in parallel, and potential downtime. After go-live, usage-based billing can drift. Flexera’s 2025 report found cloud budgets running 17% over their limits (Flexera, 2025).

Solution

Plan for significant changes. Build a migration budget that covers one-time and ongoing costs, and put cost optimization controls in place from day one: tagging, budgets and alerts, rightsizing and scheduled shutdown of idle resources. Evaluate short-term and long-term financial implications alongside operational and strategic benefits to make informed decisions about cloud adoption. The table below lists costs that are easy to miss.

4. How do you handle data transfer and integration?

Interdependencies between datasets and applications create major risks during cloud migration, including data loss. Dependencies can be hard to separate, which makes migrating without disruption complex. Interwoven dependencies also make data synchronization and security harder to get right, and the customization needed for a smooth transition can raise costs.

Solution

The best defense is a detailed plan with many checkpoints. Start by understanding your current environment and every dependency. Choose your integration approach for new and existing systems, then add data integrity checks (record counts, checksums and sample validation) at each stage. Many tools can automate and streamline extraction and migration, then monitor and validate the process. For large data sets, plan transfer time realistically against available bandwidth.

5. How do you solve application compatibility problems?

Application compatibility, including dependencies and integration with existing systems, can create hardware, software and network challenges. Sometimes finding a compatible version or a suitable cloud alternative slows or complicates the process.

For example, some applications require hardware components or licensing tied to physical machines that are not available in the cloud. Virtualized environments do not always replicate the exact hardware characteristics needed for optimal performance, and some devices in offices (label printers, scanners, badge readers, specialty instruments) expect a server on the local network.

Solution

Map interdependencies and compatibility, test for potential issues, tie each application to a business objective, then assess the level of complexity and what outside help may be needed. Choose a migration approach per application:

• Rehost (lift and shift): move as is, fastest but least optimized.
• Replatform: make modest changes, such as moving to a managed database, to gain cloud benefits.
• Refactor: rework the application’s code or architecture to suit the cloud.
• Replace: retire the application and adopt a SaaS alternative.
• Retain: keep it on-premises, at least for now, when the cost or risk of moving is too high.

6. How do you close skills and resource gaps?

IT teams are often highly trained in on-premises systems, and a significantly new platform can create gaps in skills and capacity. If your team lacks experience managing cloud infrastructure and services, you face training needs and new compliance responsibilities at the same time as the migration itself.

Capacity is the other gap. During a migration your team still has to run the business, and in distributed companies that includes supporting offices in many cities.

Solution

Prepare in advance with training and upskilling for everyone who will run the new environment. With so many risks during migration, organizations cannot afford to overlook the human element. Build a cloud-centric culture and encourage buy-in and skilled use of new systems.

To minimize risk, particularly during large migrations, bring in outside experience. Many organizations use specialist partners for cloud architecture and local technicians for the physical work at offices: network changes, device reconfiguration and decommissioning. Techmate provides IT project and rollout field support with vetted technicians in 450+ US cities, so your internal team can stay focused on the migration itself.

7. Why do planning and strategy make or break a migration?

Meticulous planning is the foundation of every successful cloud migration. A lack of mapping, planning, testing and strategy is behind many unforeseen cloud costs, disrupted business processes, frustrated teams and lost network resources. Make sure the cloud platforms you consider fit your business at every stage of the migration.

Planning also means deciding what should not move. Flexera’s 2025 report found that 21% of cloud workloads had been repatriated to non-cloud environments (Flexera, 2025), a reminder that the cloud is not the right home for every workload. Our post on physical infrastructure in a cloud-first world covers this trend.

Solution

Create a written cloud migration strategy. A practical sequence:

1. Define business objectives and how you will measure success (cost, performance, resilience, speed of delivery).
2. Inventory applications, data, dependencies and the sites and users each one serves.
3. Choose a migration approach per application and group workloads into waves.
4. Select the cloud provider and architecture, including security and network design.
5. Assess each office: bandwidth, firewall capacity, local devices and who will be onsite during cutover.
6. Run a pilot wave, review lessons learned and adjust the plan.
7. Migrate remaining waves, then decommission old systems on schedule.

Careful planning upfront can save you from disaster once the process starts.

8. What should you plan for after cloud migration?

Consider the challenges that arise after migration, including slow application performance and limited network bandwidth. As with any significant IT change, expect a period of adjustment and tuning. Slow systems can cause downtime or a poor experience for customers and staff, so your strategy should state how you will handle issues in the days and weeks after go-live.

Dependencies also change. Uptime Institute reports that third-party providers, including cloud, internet, telecom and colocation firms, account for about two-thirds of publicly reported outages it has tracked (Uptime Institute, 2026). After migration, your offices depend more heavily on internet circuits and providers, so redundant connectivity at critical sites matters more than before.

Solution

Continuous monitoring and security management plus real-time optimization will get your systems up to speed faster. Keep security controls active as you tune the new environment to prevent a larger issue. Update your IT disaster recovery plan to reflect where systems now run. As you monitor performance, return to your success measures and ROI, including scalability and total cost.

How does cloud migration affect branch offices and remote sites?

For multi-location companies, cloud migration shifts work rather than removing it. Servers leave the closet, but the network becomes more important. Plan for these site-level tasks:

• Bandwidth and circuit upgrades: traffic that used to stay local now goes to the cloud.
• Firewall and SD-WAN changes: new routes, security policies and sometimes new equipment.
• Device reconfiguration: printers, scanners and specialty devices that pointed at local servers.
• Cutover support: a technician onsite during the change window to test and fix local issues.
• Decommissioning: removing old servers, wiping drives and documenting disposal.

Examples by industry: law firms moving document management to the cloud need tested scanning and printing at every office; banks need branch network changes inside strict change windows; retail locations need point-of-sale systems validated before stores open. In each case, smart hands IT services can carry out the local steps while your central team runs the migration remotely.

What are the most common cloud migration mistakes to avoid?

• Migrating everything at once instead of in tested waves
• Skipping a dependency map and discovering broken integrations after cutover
• Ignoring office bandwidth and network equipment until users complain
• Leaving old environments running long after migration, paying twice
• No cost controls or tagging from day one
• Assuming the provider handles all security; most cloud security is a shared responsibility

Is planning essential for a successful cloud migration?

Yes. Moving to the cloud presents common challenges, but for most businesses the long-term benefits outweigh the risks. To reduce problems, create a strategy that runs from pre-migration through post-migration. Consider outsourcing routine and onsite tasks to a third-party team of experts to free up valuable bandwidth for in-house talent.

Frequently Asked Questions

What are the key challenges in cloud migration?

The key cloud migration challenges are data security and compliance, downtime, cost management, data transfer and integration, application compatibility, skills gaps, planning and post-migration performance. For companies with many offices, network readiness at each site is another frequent challenge, because more traffic now crosses internet circuits instead of staying on the local network.

What are the 4 R’s of cloud migration?

The four Rs most often cited are rehost (lift and shift), replatform (small changes to gain cloud benefits), refactor (rework the application for the cloud) and replace (move to a SaaS product). Larger frameworks add options such as retire, retain and relocate. Choose an approach per application based on value, risk and cost.

What steps can be taken to minimize downtime during cloud migration?

Create a detailed plan before execution, migrate in waves, and schedule cutovers in low-usage windows with a tested rollback plan. Use failover options where possible, monitor and test in real time, and keep support available after go-live, including someone onsite at key offices to resolve local connectivity and device issues.

How can data security and compliance issues be addressed during cloud migration?

Choose a cloud provider that meets your security and compliance requirements, classify data before moving it, encrypt data in transit and at rest, and use least-privilege access for migration accounts. Review configurations before go-live, keep backups and a recovery plan, and confirm with your compliance team that regulated data lands in approved locations.

How long does a cloud migration take?

It depends on the number of applications, data volumes, dependencies and how much refactoring is needed. A few simple workloads can move in weeks, while an enterprise program with many applications and sites can run a year or more. Waves, a pilot and a firm decommission schedule keep timelines realistic.

Do you still need onsite IT support after moving to the cloud?

Yes. The cloud removes servers from your offices, but people still use laptops, printers, Wi-Fi, firewalls and conference room equipment that need hands-on work. Networks become more critical after migration, so many companies keep onsite support available for circuit issues, hardware swaps and new office setups.
