# 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 ev-cloud 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.

### What does a phased CPO migration look like?

Typical waves move a non-critical site first, keep the current CPMS as one backend, add a charger-facing gateway, then expand site groups once reconnect and session quality hold. Billing and roaming stay on current systems until you choose to move them.

### Can I roll back if a wave fails?

Yes. Because chargers point at the gateway, you can send a site group back to the previous backend without a truck roll, as long as the old system is still in the routing plan.
