Evaluate a migration through business rules, response time, resource use and a rollback rehearsal. Explore the application, experiment and result together in the lab.
The starting scenario is shown below. Changing inputs requires JavaScript.
Enter all three values to compare current and target time. Minutes: 0–1,440; monthly runs: a whole number from 0–1,000,000.
How is this calculated?
Monthly difference = (current minutes − target minutes) × monthly runs ÷ 60. This assumes the target is achieved. Whether the time can be used elsewhere depends on the workflow. Inputs stay in your browser.
THE WORKING METHOD
How a modernization project works
Health check
Review critical workflows, dependencies and support status, then rank the work.
Incremental transition
Start with a bounded workflow and keep a rollback path.
Parallel operation
Compare old and new results using the same task and data.
Maintenance
Agree updates, monitoring and responsibilities in advance.
HUMAN + AI
Where does AI fit in the work?
AI assists discovery, documentation and draft code. People own design decisions, validation and code review. Case steps make each contribution explicit.
