Oracle Forms Migration
Challenges
• Availability of Oracle Forms developers
• Availability of System Matter Experts (SMEs)
• Non-trivial = Significant effort and resources
• Ensuring new application implements all business rules
• Agreeing on new application look and feel
• Implementing new process flows
• Managing scope creep
• Getting buy-in from existing “power-users”
• Training end users (new and old)

Oracle Forms Migration
Strategy
• Push as much business logic into the Database as possible
• Identify a suitable functional section for the Proof-of-Concept
• Secure SMEs for functional input and direction
• Train developers in the new technology
• DO NOT try and replicate Oracle Forms UI or UX
• Generally, bend the requirements, not the tool
• Ensure the new apps are modern Web apps – simple, intuitive, easy to use
• Ensure the apps work on any device – Desktop, tablet, smartphone
