The challenges of IBM i/AS400 green screen modernization include:
- Compatibility issues: Ensuring the new GUI integrates seamlessly with the existing backend without disrupting functionality.
- Cost and time: While modernization is less costly than a full rewrite, it still requires investment in expertise, tools, and testing.
- Data security: Ensuring the updated interface maintains the same security standards as the legacy system.
- Skill gaps: Modernization requires developers with expertise in both legacy systems and modern technologies, which can be hard to find.
- User resistance: Long-term users might resist changes, requiring additional training to adapt to the new interface.
These can be managed with the right strategy and expertise.
