Real-World Success Stories in Application Modernization
Case Studies
Banking Core Modernization
A regional bank ran daily transactions on a legacy AS/400 system that limited new product launches. Zymr created a modernization roadmap, migrated transaction processing to cloud, and refactored services as APIs. New customer features launched twice as fast, and cost of operations went down by thirty percent.

Application Modernization: Time and Cost
Modernizing legacy applications is a strategic investment that strengthens your technology foundation and positions your business for future growth. Both the timeline and the cost of application modernization depend on your systems’ complexity, the number of integrations, and how far you want to advance on the modernization spectrum.
Typical Timelines
Small to midsize application modernization projects such as updating a standalone legacy business tool or refactoring individual modules are often completed in three to four months.Enterprise-scale efforts like migrating complex monolithic systems to microservices, adopting cloud-native architecture, or integrating with critical business platforms usually take six to twelve months or longer, depending on the number of systems and data migration needs.
Cost Expectations
Straightforward modernization initiatives, such as rehosting or code upgrades for core applications, can start around $30,000 to $50,000. More involved projects, such as full legacy system transformation, cloud migration, microservices reengineering, or enterprise application reengineering, may begin at $70,000 and scale upwards based on overall scope, compliance requirements, and customization.
What Affects Time and Cost
The main drivers of time and budget are:
- The depth of modernization needed (rehosting, refactoring, or full rebuild)
- The number and complexity of existing integrations
- Regulatory or security mandates in your industry
- The readiness of supporting infrastructure and in-house systems
- Required downtime minimization and change management planning

About Application Modernization
How do I know when it’s time to modernize a legacy application?
Answered by: Principal Application Architect"If updates are slow, integrations are difficult, or support costs keep rising, it’s time to consider modernization. When your system cannot connect to cloud tools, hinders security updates, or blocks digital strategy, a planned upgrade is your best move."
How do you minimize risk and prevent business disruption?
Answered by: Modernization Program Manager"Incremental migration and continuous testing are key. We monitor performance, run migration in stages, and keep legacy systems live until the new app is proven. Regular check-ins and business user feedback reduce surprises."
Do you support continuous optimization after go-live?
Answered by: AMS Delivery Lead"Absolutely. Our support covers patching, upgrades, performance management, and advice on the next wave of improvements for your apps so your investment pays off year after year."
What approach do you recommend: rehosting, refactoring, or rebuilding?
Answered by: Senior Project Manager
Answered by: Lead Modernization Engineer"We evaluate each app case by case. Rehosting moves your app to the cloud with minimal change. Refactoring tunes code and adds new features for better performance and security. Full rebuilding is rare but right for very outdated or high-risk systems. Our experts recommend the best fit after a careful assessment."
Can you modernize applications for compliance-heavy industries like finance or healthcare?
Answered by: Compliance SME"Yes, we have deep experience navigating tight regulations, data security, and privacy requirements. Modernization is always done with compliance, audit trails, and industry standards in mind."
