Migrating Off a Legacy Integration
Old integrations eventually outlive their usefulness, whether because the connected service is being retired, the original build is fragile, or your needs have simply changed. Moving off one safely takes more thought than building from scratch.
This article explains how we retire a legacy integration without disrupting the business that depends on it.
Why Migration Needs Care
A live integration is often quietly doing more than anyone remembers.
- Other processes may secretly rely on it.
- Documentation is often incomplete or out of date.
- Switching off too soon can lose data in flight.
- Edge cases only surface under real conditions.
Our Approach
We replace the old with the new gradually and reversibly.
- Map exactly what the old integration does today.
- Build and test the replacement alongside it.
- Run both in parallel to compare results.
- Switch over once we are confident, then retire the old.
Frequently Asked Questions
Will there be downtime during the switch?
We aim for none. Running old and new in parallel lets us cut over smoothly, usually without any interruption.
What if the new integration has a problem?
Because the old one stays available until we are confident, we can fall back safely if anything unexpected arises.
