Modernize your cloud. Maximize business impact.

83% of data migration projects either fail or exceed their budgets and schedules. For small and mid-sized businesses (SMBs), where resources are already stretched, these setbacks can derail digital transformation plans and lead to lasting operational inefficiencies.
Cloud migration promises scalability, performance, and long-term savings, but reaching those outcomes depends on more than just technical execution. From missing dependencies and underplanned cutovers to skill gaps and unexpected egress fees, SMBs often encounter challenges that delay timelines and increase costs.
This blog outlines 10 common cloud migration challenges faced by SMBs, and provides specific, AWS-based strategies to address each one, before they impact the budget or business continuity.
Key takeaways:
- Plan with precision: A clear, phased migration roadmap based on business priorities helps avoid disruption and inefficiencies.
- Map dependencies early: Hidden integrations and data flows can break migrations. Use AWS discovery tools to catch them upfront.
- Security and governance must be built-in: Misconfigurations post-migration are common. Proactive IAM, Config, and CloudTrail setups are essential.
- Cloud fluency matters: Empowering internal teams with training reduces missteps and accelerates adoption.
- Optimization doesn’t end at cutover: Post-migration tuning such as right-sizing, automation, and analytics unlocks the full business value of the cloud.
Why do cloud migrations stall for SMBs? 10 common challenges and how to avoid them

The path to modernization can often get complicated by technical constraints, organizational gaps, and legacy dependencies that aren’t obvious until systems are already in transition.
Even with the promise of scalability, cost-efficiency, and real-time access, cloud migrations can encounter roadblocks that delay timelines, increase risk, or leave cloud environments underutilized. Challenges like missing dependency mapping, unclear ownership, skill gaps, or lack of governance don't just slow progress, they reduce the long-term business value of the cloud.
The SMBs that succeed with cloud migration are the ones who anticipate these challenges early, tackling them with clear strategy, technical readiness, and the right AWS tools:
1. Undefined migration roadmap and prioritization
One of the most common pitfalls in SMB cloud migrations is starting without a clear, phased roadmap. Many teams attempt to migrate all applications and data at once, resulting in bottlenecks, missed dependencies, and operational downtime.
Without understanding inter-system dependencies, critical workloads may break mid-migration. This lack of planning also makes it harder to align migration phases with business goals like improving availability, reducing licensing costs, or enhancing compliance.
How to avoid this challenge: Build a structured, phased migration plan that prioritizes business value and technical readiness:
- Use AWS Application Discovery Service and Systems Manager Inventory to uncover system interdependencies and build a full asset inventory.
- Run a Data Modernization Assessment and AWS Migration Evaluator to prioritize workloads based on cloud readiness and business value.
- Create a phased migration roadmap in AWS Migration Hub, tagging workloads by criticality and tracking progress in real time.
Pro tip: AWS partners like Cloudtech can ensure SMBs don’t waste effort on low-impact moves. They kick off each engagement with a modernization assessment to prioritize workloads based on ROI, compliance needs, and performance bottlenecks.

2. Siloed technical and business alignment
A major challenge during cloud migration is the disconnect between technical execution and business priorities. Engineering teams might focus on moving infrastructure quickly, while business leaders expect improvements in service levels, agility, or cost savings.
Without early alignment, SMBs risk migrating workloads that don’t support key KPIs, such as customer SLAs, analytics performance, or regulatory timelines. This misalignment can result in either underpowered applications or overengineered architectures that inflate AWS bills without delivering business value.
How to avoid this challenge: Ensure technical plans are directly tied to business outcomes from the start:
- During the Align phase, interview stakeholders to define business-aligned KPIs like SLAs, RTOs, or cost-per-transaction metrics.
- Use the AWS Well-Architected Tool to evaluate workloads against operational, security, and financial goals, guiding service choices like EC2 vs. Lambda.
- Implement CloudWatch Synthetics, X-Ray, and Resource Groups with KPI-based tagging to monitor performance and maintain accountability across teams.
Pro tip: Cloudtech bridges the gap between business and technical teams by using a business-first approach in their modernization strategy. This could be reducing reporting delays in financial systems or improving uptime for healthcare portals. Hence, both sides stay focused on outcomes, not just infrastructure.
3. Lack of visibility into application dependencies
It’s easy to underestimate how interconnected their applications are until they start migrating. Legacy systems often include undocumented APIs, batch jobs, shared databases, or third-party connectors. Without a full understanding of these dependencies, critical workflows can break post-migration.
This causes downtime, data inconsistencies, or integration failures between apps that previously functioned in the same on-prem environment.
How to avoid this challenge: Map out all upstream and downstream connections before any workload is moved:
- Use AWS Application Discovery Service and Systems Manager Inventory to map application relationships, software stacks, and traffic flows across systems.
- Build a dependency matrix covering APIs, databases, file shares, and cron jobs; validate with test cutovers using Route 53 traffic shifting and Elastic Load Balancers.
- Monitor behavior during staging tests with CloudWatch Logs and AWS X-Ray to catch missing links before production migration.
Pro tip: Cloudtech conducts deep discovery and mapping during the Discover phase using AWS-native tools, ensuring all dependencies are accounted for. This avoids common SMB pitfalls like customer portals losing access to shared databases or payroll systems breaking due to missing cron triggers post-migration.
4. Downtime and failed cutovers
One of the biggest risks during migration is downtime caused by poor cutover planning. SMBs might switch production traffic to cloud environments without running prior rehearsals, leading to incomplete data syncs, broken integrations, or even full outages. Without automation or rollback mechanisms in place, a failed cutover can disrupt customer access, delay operations, and erode trust.
These risks are amplified for SMBs handling transactional systems like ERPs, EHRs, or e-commerce platforms, where even short outages can impact revenue or compliance.
How to avoid this challenge: Use automated replication, pre-tested switchover strategies, and orchestrated workflows to reduce risk:
- Use AWS Application Migration Service (MGN) to perform continuous block-level replication of on-prem systems, ensuring up-to-date copies with minimal lag.
- Set up blue/green environments and perform controlled cutovers using Route 53 traffic policies or Elastic Load Balancer listeners to switch traffic safely.
- Orchestrate the final cutover using AWS Systems Manager Automation, ensuring steps like data freeze, DNS updates, and user communication are executed in the right sequence.
Pro tip: Cloudtech de-risks cutovers by simulating transitions in staging environments first, using Route 53 weighted routing and Amazon CloudWatch metrics to validate performance before flipping production traffic. Their team also builds rollback plans using AMIs and versioned configurations to ensure business continuity.
5. Insufficient governance and access controls
Many SMBs enter the cloud without a structured governance model, leading to overly broad permissions, exposed resources, and compliance blind spots. In the rush to migrate, critical elements like role-based access, audit logging, or policy enforcement are often skipped, creating long-term risks around data security and accountability.
This is especially concerning for SMBs in regulated industries like healthcare or finance, where improper access controls or missing audit trails can result in compliance violations and security incidents.
How to avoid this challenge: Establish cloud governance and security controls from day one of the migration:
- Define IAM roles and policies using least privilege, scoped by team or workload, and apply tag-based access control.
- Enable AWS CloudTrail and AWS Config across all regions to monitor, audit, and enforce compliance in real time.
- Use AWS Organizations with Service Control Policies (SCPs) to set permission boundaries and prevent unauthorized usage across accounts.
Pro tip: Cloudtech pre-configures security and governance frameworks tailored for SMB environments, embedding IAM, KMS, CloudTrail, and AWS Config as standard from the discovery phase. This helps SMBs meet regulatory requirements early, especially in sectors like healthcare where compliance isn't optional.
6. Performance discrepancies post-migration
After moving to AWS, SMBs may discover that workloads behave differently than they did on-prem, whether it’s slower API response times, unexpected timeouts, or batch jobs exceeding runtime windows. These discrepancies usually stem from mismatched instance types, improper database configurations, or network latency introduced by architecture changes.
Without pre-migration benchmarks or post-migration tuning, these issues can erode user experience and create frustration for internal teams or customers, especially in real-time applications like appointment booking, financial transactions, or healthcare reporting.
How to avoid this challenge: Validate performance in staging before go-live, and use AWS-native services to continuously optimize:
- Monitor metrics with Amazon CloudWatch and trace service behavior with AWS X-Ray to detect performance bottlenecks.
- Simulate peak loads in staging using AWS Fault Injection Simulator or custom load tests to validate scalability.
- Optimize resources by enabling Auto Scaling, adopting Aurora Serverless v2, or migrating to AWS Lambda where applicable.
Pro tip: Cloudtech performs staged performance testing before full cutover, using CloudWatch dashboards and X-Ray traces to baseline workload behavior. They also recommend right-sized services (like Graviton-powered EC2 or Aurora Serverless) to ensure post-migration environments are optimized, and not just operational.
7. Limited internal cloud expertise slowing execution
Many SMBs start cloud migration without deep AWS knowledge, leading to misconfigurations, inefficiencies, and slow adoption. Teams unfamiliar with concepts like IAM policies, auto-scaling, or cost monitoring can unintentionally create security gaps or overspend.
How to avoid this challenge: Enable teams with focused, role-based learning and controlled environments:
- Enroll team members in tailored AWS Skill Builder learning paths based on their roles (e.g., developer, operations, finance).
- Use AWS Control Tower to set up sandbox accounts with guardrails for safe experimentation.
- Assign scoped IAM roles and budgets to allow hands-on practice without risking production or cost overruns.
Pro tip: Cloudtech provides embedded enablement plans alongside migration, helping SMB teams gain AWS fluency while building real-world environments.
8. Security gaps left unchecked post-migration
After migrating to AWS, many SMBs overlook their part of the shared responsibility model, assuming security is handled by default. This leads to misconfigurations like public S3 buckets, overly permissive IAM roles, or unencrypted data, increasing the risk of breaches and compliance violations.
How to avoid this challenge: Enforce security controls and continuously monitor for drift:
- Use AWS Security Hub and IAM Access Analyzer to detect misconfigured roles, public resources, or unapproved access patterns.
- Enforce encryption across S3, RDS, and EBS with AWS KMS, and configure VPC security groups to limit exposure.
- Activate AWS CloudTrail and CloudWatch Logs for full visibility into access and API activity.
Pro tip: Cloudtech preconfigures security guardrails during migration, such as encryption policies, IAM boundaries, and compliance packs, so SMBs meet standards like HIPAA and SOC 2 from day one.
9. Cost governance and ownership confusion
Post-migration, many SMBs struggle with unclear ownership of cloud resources and lack visibility into who’s responsible for spending. Without consistent tagging or budget monitoring, costs become difficult to allocate, leading to unplanned overruns and poor accountability across teams.
How to avoid this challenge: Establish clear billing visibility and accountability from the start:
- Use AWS Organizations to create separate accounts for departments or projects, with Service Control Policies (SCPs) to enforce limits.
- Enforce resource-level cost allocation tags (e.g., Project, Owner, Environment) using AWS Tag Policies.
- Set AWS Budgets and monitor spend via AWS Cost Explorer and Cost and Usage Reports (CUR) for real-time visibility.
Pro tip: Cloudtech configures billing guardrails during migration, aligning technical usage with financial ownership so SMBs can track, allocate, and optimize cloud costs without surprises.
10. Missed optimization post-migration
A successful migration doesn’t end with workloads running in the cloud. Many SMBs leave their systems in a “lifted” state, underutilizing AWS-native services and missing chances to streamline operations, enable automation, or unlock analytics and AI capabilities. This limits the long-term value of the move.
How to avoid this challenge: Treat migration as the foundation for modernization:
- Use AWS Glue to clean and structure data for analysis or downstream systems.
- Query and analyze with Amazon Athena or Amazon Redshift to unlock reporting and insights across teams.
- Integrate Amazon EventBridge for automation triggers or Amazon Q Business to enable AI-driven dashboards and document processing.
Pro tip: Cloudtech helps SMBs go beyond rehosting, architecting for scale and insight by embedding data pipelines, analytics readiness, and automation hooks from the start.
Each of these challenges, if overlooked, can significantly delay deployment, raise costs, or introduce technical debt. By addressing them early and using AWS-native tools effectively, SMBs can migrate confidently and build a sustainable foundation for growth.

FAQs
1. How early should SMBs start involving non-technical stakeholders in the migration process?
Ideally, from day one. Involving finance, compliance, and operations teams early helps align technical decisions with broader business goals. For example, choosing Reserved Instances vs. On-Demand impacts long-term budgeting, something finance should weigh in on during the planning phase.
2. What’s the best way for SMBs to track migration progress in real time?
AWS Migration Hub provides a centralized dashboard to monitor each application's migration status, including dependencies, data replication health, and cutover readiness. It’s especially useful for SMBs managing phased migrations with limited oversight capacity.
3. How do SMBs prevent “cloud sprawl” during and after migration?
Cloud sprawl can be prevented by enforcing strict tagging policies, using Service Control Policies (SCPs) in AWS Organizations, and limiting who can provision new services. Setting automated guardrails during migration keeps the environment clean and cost-efficient.
4. What if an SMB has partial workloads already in the cloud, can they still use a structured migration strategy?
Yes. Even if some apps are already in AWS, a phased and strategic migration plan still applies. SMBs can revisit architecture with the AWS Well-Architected Tool, restructure resource groups, and use AWS Config to baseline current-state governance before expanding further.
5. How can SMBs balance speed and risk during migration?
Speed shouldn’t come at the cost of resilience. SMBs should adopt a “minimum viable migration” mindset. Start small (e.g., analytics workloads), validate performance, then scale. This reduces risk while still showing early wins to internal stakeholders.
