Common Modernization Challenges
Prioritize high-impact, low-risk modules first.
Ensure comprehensive test coverage before refactoring.
Involve stakeholders in the roadmap planning.
Focus on data integrity during migration.
Attempt a 'big bang' rewrite without a phased plan.
Ignore the underlying business logic during updates.
Neglect documentation for the new architecture.
Underestimate the time needed for data cleaning.
Modernizing for the Cloud
A successful legacy to cloud migration involves more than just moving servers; it requires adopting a cloud-native mindset to leverage auto-scaling and managed services.
Real-time observability is a hallmark of modernized systems.
