# EV charging platform migration for CPOs

> This solution is built for operators replacing a legacy CPMS or CSMS without forcing every charger, backend, and business workflow to move at once. The focus is phased migration, rollback, and backend coexistence.

Use GridOS to migrate CPO infrastructure in phases, keep chargers online during transition, and avoid a risky big-bang CPMS or CSMS replacement.

## Audience

Charge Point Operators modernizing a legacy charging backend.

## Best for

CPO teams that need staged migration, multi-backend routing, and a safer path away from a locked-in CPMS or CSMS.

## Pain points

- A direct backend replacement would force too much change at once.
- Different charger groups need to migrate at different times.
- Roaming, billing, and support workflows still depend on the current platform.
- The team needs rollback options if rollout quality drops.

## Outcomes

- Run old and new backend systems in parallel during rollout.
- Preserve charger connectivity while vendor and workflow changes happen behind the scenes.
- Reduce migration risk without giving up long-term platform flexibility.
- Move from pilot to production with a clearer commercial and technical sequence.

## FAQ

### When is a migration-focused platform layer worth it?

It becomes valuable when the fleet, integrations, or partner dependencies make a direct one-step replacement too risky for operations, revenue, or support teams.

### Does this require replacing the existing CPMS immediately?

No. The main point is to create a safer transition layer so systems can coexist while migration happens in waves.
