How long does a software migration take?

There is no standard migration timeline. Duration depends on the size and complexity of the application, architecture, documentation, dependencies, database, target technology, testing requirements, team capacity, migration strategy, and business constraints.

What is the biggest factor affecting software migration cost?

There is no single factor that determines cost. Codebase complexity, migration scope, required engineering effort, target technology, data migration, integrations, testing, and available resources – all contribute. In practice, hidden complexity is often more important than raw code volume.

Does the number of lines of code determine migration time?

No. Lines of code help estimate scale. But they do not show how difficult the system is to understand or change. Two applications with the same number of lines can have different architectures, dependencies, documentation, test coverage, and business logic.

How does poor documentation affect software migration?

Poor documentation increases the amount of discovery work required before and during migration. Developers need to know the architecture, dependencies, business rules, or deployment processes. They may need to reconstruct this information from the source code and input from internal experts. This can increase migration time.

Can AI automate software migration?

AI and other automation technologies can speed up parts of a migration. They do not eliminate the need for engineers. Humans should validate decisions involving business logic, architecture, compatibility, exceptions, and system behavior. The most effective approach is usually a combination of automation and expert review.
