 This guide explains how to move a Public Gateway from [Legacy mode](https://www.scaleway.com/en/docs/public-gateways/concepts/#ipam) to IPAM mode. Only gateways in IPAM mode will be compatible with the new v2 of the Public Gateways API. v1 of the API is deprecated, and will be removed later this year.
 In the legacy setup, DHCP and DHCP reservations are managed with dedicated resources and referenced in the gateway network.
-In v2, the public gateway is migrated to use IPAM (IP Address Management) mode.
+In IPAM mode, these functionalities are managed by Scaleway IPAM.
 In 2023, DHCP functionality was moved from Public Gateways to Private Networks, DHCP resources are now no longer needed.
