On-premises infrastructure to cloud migration affects how your organization operates and secures its data. Before moving to the cloud, you must ask the right questions. Knowing what’s at stake ensures a smoother transition and helps you avoid costly missteps.

This comprehensive guide outlines seven critical questions to evaluate before, during, and after your cloud migration journey. By addressing these questions upfront, you can confidently make informed decisions and set your organization up for long-term cloud success.

1. Which applications and workloads should you migrate first?

Not all applications and workloads are created equal. Some are mission-critical and ready for cloud migration, while others might require extensive reconfiguration or are better left on-premises for now. 

Your on-premises to cloud migration can deliver early wins and minimize disruption when you decide which workload to prioritize. The following core applications are often ideal starting points: 

• Cloud-compatible
• High scalability requirements
• Performance limitations on legacy infrastructure 

On the other hand, legacy systems with tight on-premises integrations or compliance constraints might require more planning or alternative solutions, such as a hybrid cloud. 

Rushing to migrate everything at once without a clear prioritization strategy leads to unnecessary costs, service downtime, or data integrity issues. A phased approach, starting with low-complexity, high-impact workloads, allows you to learn, adapt, and improve processes along the way.

Research shows that 62% of companies migrate to the cloud for greater flexibility, while 47% seek improved cost control. However, to make this migration work for your organization, you must ask this question upfront. It sets the foundation for your entire cloud success strategy.

2. What’s your current infrastructure footprint and system dependencies?

Before doing on-premises to cloud migration, you need a clear picture of your current infrastructure footprint. These include:

• Servers
• Applications
• Databases
• Storage
• Networking components

Equally important are the interdependencies between these elements. For instance, an application might rely on a local database, file system, or authentication service. Migrating it without accounting for those connections could cause system failures or data loss.

Many organizations underestimate the complexity of their on-premises environments. A lack of a complete inventory and a map of system dependencies can delay, derail, or drive up the cost of migrations. 

This question ensures that your team identifies critical links between systems, avoids migrating in silos, and prevents performance issues post-migration. Using cloud assessment tools is key at this stage. 

Cloud assessment provides automated discovery, inventory management, and dependency mapping that help build an accurate picture of your IT environment. It analyzes usage patterns, highlights redundant or underutilized assets, and helps determine which components are ready for the cloud.

3. What security, compliance, and data-sovereignty rules apply?

Different industries and regions enforce unique data protection laws. For example, healthcare organizations must comply with HIPAA in the U.S., while financial institutions might be subject to PCI-DSS. 

Internationally, laws such as the EU’s GDPR or Australia’s Privacy Act impose strict rules on data handling and cross-border transfers. If you overlook these requirements during on-premises to cloud migration, you might face legal penalties, data breaches, or loss of customer trust. 

The global average cost of a data breach is $4.4 million. Even choosing the wrong cloud region could violate data sovereignty laws, requiring that data remain within national or regional borders.

By asking this question early, you can:

• Select cloud providers and configurations that meet your organization’s security and compliance standards.
• Implement the proper encryption, access controls, and audit mechanisms.
• Avoid costly regulatory missteps and reputational damage.

Once you have incorporated these considerations into your migration plan and validated them using the cloud provider’s compliance documentation, you can ensure that your cloud journey is efficient and legally sound.

4. How will you manage data transfer, bandwidth, and downtime?

On-premises to cloud migration involves moving various data across networks. Without proper planning, transferring large datasets to the cloud can overwhelm your existing network connectivity, slow down critical operations, and lead to costly service interruptions.

Downtime can significantly affect customer experience, employee productivity, and even revenue, particularly for businesses that rely on real-time systems. Key considerations include:

• How much data needs to be transferred? Identifying volume helps select the correct transfer method, whether online transfer, physical shipping (e.g., AWS Snowball), or a hybrid approach.
• What is the available bandwidth? Limited bandwidth can stretch migration timelines and increase the risk of timeouts or partial transfers.
• When should the migration occur? Scheduling data transfers during off-peak hours can help reduce disruption to users and services.
• What’s the rollback or contingency plan? If something goes wrong, you need a tested recovery strategy to avoid prolonged downtime or data loss.

Asking these questions and assessing your network connectivity readiness helps you design a smooth migration with the least business impact.

5. What tools and automation will support discovery, replication, and cutover?

The right tools streamline the process of on-premises to cloud migration. This question focuses on selecting the technologies and platforms that will support discovery (identifying and analyzing your existing infrastructure), replication (copying data and applications to the cloud), and cutover (switching from the old system to the new cloud environment).

Manual migration is a risky, time-consuming, and error-prone process. Automation simplifies and accelerates the process using:

• Discovery tools. These provide a detailed inventory of servers, applications, configurations, and interdependencies, helping teams understand what needs to be moved and in what order.
• Replication tools. These continuously copy data and applications to the cloud, enabling real-time synchronization and reducing the risk of data loss.
• Cutover tools. These help orchestrate a seamless switchover with minimal downtime by automating service redirection, final syncs, and system testing.

The benefits of using migration automation include:

• Accelerated timelines with fewer manual tasks
• Reduced risk of missing dependencies or configurations
• Smooth transitions with better rollback and recovery options
• Easier to migrate large volumes of data and systems

Popular examples include AWS Migration Hub, Azure Migrate, Google Cloud Migrate, Carbonite Migrate, and third-party platforms such as CloudEndure and Zerto. When you ask this question, you’re laying the groundwork for a successful move to the cloud.

6. How do cloud costs compare over time?

On-premises infrastructure typically requires large upfront capital expenditures (CapEx), including investments in hardware, software licenses, and data center facilities. 

In contrast, cloud services shift most of those costs to operational expenditures (OpEx), offering a pay-as-you-go model based on usage. While the cloud can reduce the need for significant capital investments, it might lead to higher long-term operating costs if not adequately managed. 

Workload sprawl, unoptimized storage, or overprovisioned resources can quickly inflate bills. This is why comparing the total cost of ownership (TCO) over time is crucial.

You must consider the following:

• How do upfront CapEx savings compare to long-term OpEx spending?
• Will cloud costs increase as the organization expands, or can they be managed through scaling and automation?
• Are there hidden costs in cloud licensing, third-party tools, or premium support tiers?
• Is your team ready to monitor and optimize usage to avoid bill shocks?

By asking this question early on, you can develop a financial model that accurately reflects real-world cloud usage and establish realistic return on investment (ROI) expectations.

7. What skills and change management do you need for success?

On-premises to cloud migration involves a shift in people and processes. Cloud environments require a different set of skills than traditional IT operations. Your team might need to learn new tools, security protocols, and DevOps practices. 

Without proper training or support, even a technically sound migration can fail due to operational missteps, misconfigurations, or internal resistance. At the same time, change management is crucial for a smooth transition. 

Change management involves preparing your teams for new workflows, updating policies and governance models, communicating clearly across departments, and addressing any resistance to change.

A managed services provider (MSP) can fill your skill gaps. They bring cloud-certified professionals, migration experience, and ready-made change-management frameworks. They can:

• Assess your team’s current capabilities and provide targeted training.
• Handle complex technical tasks while mentoring internal staff.
• Implement best practices for governance, security, and operations.
• Guide your organization through cultural and procedural shifts.

An MSP can help you navigate the human elements of a successful cloud migration.
