Migrating Legacy PHP / .NET Applications to Django + React.js/Next.js
Modernize without breaking systems
See How We Build for Complex BusinessesLegacy PHP and .NET applications often become difficult to maintain and scale over time. As expectations grow, these systems struggle to keep up, creating risks for performance, security, and growth.
Who This Is For
We usually work best with teams who know building software is more than just shipping code.
This is for teams who:
Companies running legacy PHP or .NET systems
Businesses facing performance and scaling issues
Teams planning modernization without downtime
Organizations needing better security and flexibility
Companies preparing for future product growth
This may not fit for:
Projects building new apps from scratch
Teams unwilling to refactor legacy systems
Businesses expecting instant full rewrites
Companies without stable existing systems
Teams not ready for phased migration
the real problem
Legacy systems slowing business growth
Outdated applications are hard to maintain, expensive to run, and difficult to extend. Businesses face performance issues, security risks, and limited flexibility. Full rewrites feel risky, often threatening stability and continuity.
how this is usually solved
(and why it breaks)
common approaches
Attempting complete rewrites in one go
Patching legacy systems without long-term fixes
Ignoring architecture during migration
Delaying modernization due to fear of risk
Underestimating data and dependency complexity
Where these approaches fall short
Leads to high-risk project failures
Creates downtime and business disruption
Results in inconsistent system behavior
Increases long-term maintenance burden
Fails to deliver real performance improvements
