I spent most of 2025 working on the migration of approximately 20 business-critical workflows from Oracle Process Cloud Service to Camunda 8 SaaS. The challenge wasn't just moving process definitions — it was migrating running processes with live data, maintaining business continuity, and improving the processes along the way.
Around 20 business processes, each with its own integrations, business rules, and user tasks. Some had been running in Oracle PCS for years with thousands of historical instances. This wasn't a weekend project — it was a sustained, methodical effort spanning most of the year.
You can't just redraw a process in a new tool and call it done — not when there are running instances that need to complete. I wrote migration scripts that extracted running process state from Oracle PCS, mapped it to Camunda 8's data model, and safely injected it into the new platform. Every running instance had to land in the correct process step with all its data intact. No lost cases, no duplicates, no data corruption.
A migration is an opportunity. Instead of recreating Oracle PCS workflows 1:1 in Camunda 8, I re-engineered them. Some processes had accumulated workarounds and dead paths over years. The migration was a chance to simplify, optimize, and align with current business rules. Every process came out cleaner and more maintainable than it went in.
The business can't stop while you migrate its processes. Customer service agents needed to keep processing cases, members needed to keep getting their payouts, and compliance requirements couldn't be paused. I ran both systems in parallel during cutover periods, validated data integrity at every step, and had rollback plans for every migration batch.
