Seamless charging migrations with one OCPP proxy
Connect every charger to one URL you control and decide where its OCPP data goes. Do the whole migration while still live on your old platform, then flip the switch with no interruption for drivers.

Running two systems at once is the real risk
Migrations rarely flip in a single moment, so for weeks part of your network lives on the old platform and part on the new one. Drivers have to charge across both, billing runs through two systems, and pricing is maintained in two places. Every duplicated surface is a chance to turn a driver away, bill a session wrong, or let a price drift out of step.

Do the whole migration before you flip
The proxy sits in front of your chargers on one URL, so you prepare and test everything while it still forwards to your current platform.
- Step 1
Connect every charger to one URL
Point your whole estate at a single custom proxy URL that you own and control.
- Step 2
Keep forwarding to your current platform
The proxy passes OCPP traffic straight through, so nothing changes for drivers while you prepare.
- Step 3
Build and test Monta in parallel
Set up users, sites, pricing and roaming on Monta and test it end to end before anyone moves.
- Step 4
Group, monitor and route on the fly
Group chargers, watch live traffic, and decide where each group’s data is forwarded.
- Step 5
Flip the whole estate in one move
When everything is verified, switch every charger to Monta at once and go live in minutes.
Two systems at once vs one OCPP proxy
The same migration, with and without a stretch of running two platforms side by side.
| Running two systems in parallel | One OCPP proxy with Monta | |
|---|---|---|
| Driver access | Must work on old and new at once | One network, drivers never notice |
| Billing | Split across two systems | Settled in one place |
| Pricing | Maintained in two platforms | Managed once on Monta |
| Testing | Limited, live, under pressure | Full test before any driver moves |
| Go-live | Phased over weeks, side effects | One flip, live in minutes |
Your charging traffic, on your terms
Every charger connects through one proxy endpoint, so routing, grouping and monitoring stay in your hands, before, during and after the move.

One custom URL
Every charger connects to a single endpoint you own, not a backend you have to reconfigure later.

Dynamic grouping
Group chargers however you like and decide where each group’s OCPP data is forwarded.

Live monitoring
Watch connection status and OCPP traffic across the estate in real time as you migrate.

Adjust on the fly
Re-route or duplex backends without touching hardware or sending anyone to site.

FAQs
How does the OCPP proxy make a migration seamless?
It connects every charger to one URL and keeps forwarding to your old platform while you build and test Monta. When you are ready, you flip the whole estate in one move.
Do I have to run two systems in parallel during the migration?
No. The proxy lets you prepare everything in advance, so you avoid splitting drivers, billing and pricing across two platforms. You go live in a single switch.
Can I control where my OCPP data is forwarded?
Yes. Chargers connect to one custom URL, and you decide which backend each group is routed to. You can monitor and adjust the traffic on the fly.
Will it work with our hardware brands?
Our team has integrated 930+ models across 260+ brands. Mixed estates are the norm, not the exception.
What is the Monta OCPP URL?
Chargers connect to wss://ocpp.monta.app. With the proxy you point your whole estate at one URL instead of editing each charger.
Is the proxy a permanent layer we have to maintain?
No. It is a migration tool. Once you flip, your chargers run natively on Monta, with users, sites, pricing and sessions in one platform.
