How to Modernize Legacy Platforms Without Halting Business?

[BAAS | Official]

Hello everyone. We’re an international B2B provider with experience in the gambling and betting industry.
Many operators have been running on legacy platforms for years, where customization turns into crutches and updates require service downtime.
 
Let's discuss:
- Gradual Migration Strategies: How do you migrate modules (payments, KYC, game engine) without downtime?
- Tools: Containerization, feature flags, API gateways – what actually works?
- Management: How do you convince the team/investors that refactoring is necessary?
 
We invite you to share case studies.

Containerization helped reduce downtime by 70%. But encountered unexpected delays during game engine migration. Anyone solved similar issues?

Feature flags are lifesavers! Tested updates on 5% users. But data sync between modules still causes headaches.

Showed investors analysis: tech debt costs 40% more than migration. Worked. Key is providing concrete loss figures.
