Our Legacy to Cloud Migration Services

Our teams work on the migration cycle. This process has multiple steps, such as performing a project audit, architecture redesign, data transfer, and post-migration support.

Industries

Chudovo specializes in helping businesses move from outdated systems to the cloud, particularly those in heavily regulated and demanding fields. Our teams understand the unique demands of each industry, including compliance, data privacy, and the need for constant availability.

How Long Does It Take to Migrate a Legacy System to the Cloud?

The duration of migration varies and commonly depends on the system’s size, the complexity of its design, the chosen cloud platform, and the specific needs of the organization. While a single, universal schedule isn’t possible, certain factors consistently affect how long a particular project will take.

  • For smaller systems, like single-service applications that host simple integrations and a modest codebase, you can expect a timeframe of approximately four to eight weeks.
  • Mid-sized systems, which are built around several services, a decent amount of data, and a few integrations, typically require three to six months to become operational.
  • Implementing large enterprise systems, with a distributed structure, a huge amount of data, a necessity to follow strict regulations, and dependence on many other systems, can take anywhere from six to twelve months.

What do our experts say?

Andrew Vakulich
Most legacy migration projects fail at the planning stage, not during execution. Teams underestimate the actual coupling in the existing system and overestimate what can be migrated without redesign. The work starts with an honest technical assessment - what can be lifted as-is, what needs re-platforming, and what is too expensive to carry forward. Getting that answer right at the start determines the migration to deliver measurable results.

Why Businesses Should Consider Migration from Legacy Systems to Cloud?

benefits
Legacy systems age, eventually becoming less useful due to outdated runtimes, unsupported dependencies, and hardware bound to physical infrastructure. This can result in higher maintenance expenses, sluggish release cycles, and increased vulnerability to security threats.
benefits
The adaptable nature of cloud infrastructure means it can scale, adjusting computing and storage resources to fit current demands. It also reduces infrastructure costs by eliminating licensing fees for legacy middleware, hardware maintenance agreements, and the overhead of on-premise data centers.
benefits
The availability of cloud infrastructure usually reaches 99.9% uptime. It also provides security and compliance controls with major cloud platforms and maintains compliance certifications for standards (HIPAA, SOC 2, ISO 27001, GDPR).
benefits
Cloud-native architectures support automated CI/CD pipelines, which speed up software delivery, with native architectures supporting automated continuous integration and continuous deployment pipelines.

FAQ

What kind of systems have you worked with? Answer
Our teams have worked with monolithic applications, on-premise ERP systems (SAP, Oracle), legacy CRM platforms, mainframe workloads (IBM z/OS, AS/400), older web applications built on PHP, Perl, and classic ASP, file-based batch pipelines, legacy data warehouses, and Windows Services migrated to serverless or containerized environments.
What kind of delivery models do you offer? Answer
We also offer a fixed-scope delivery model, with fixed-price engagements and delivery milestones. This provides predictable project spending without any time-and-materials exposure.
How much does it cost to move from a legacy system to the cloud? Answer
Based on the complexity of the existing system, the size of the codebase, the goals of the business, and the chosen migration approach, we can provide the timeline and costs for the migration. For a mid-sized system, a lift-and-shift method generally requires four to eight weeks and costs approximately ~$30,000. If you're completely rebuilding a monolithic application's architecture into microservices, you're looking at a timeline of three to nine months and costs ~$100,000. We provide a detailed timeline estimate as part of the cloud readiness assessment.
