Migration guide to nextroute and Nextmv Routing app

For users who have previously run one of the Nextmv SDK routing templates, or the Nextmv Routing app (v0 schema), below are guidelines on how to migrate to the nextroute routing engine. We recommend upgrading to benefit from improved performance and flexibility.

nextroute is the recommended vehicle routing engine now available as part of the Nextmv platform. For existing users, this guide provides instructions on how to migrate from other templates and apps to the nextroute template and Nextmv Routing app (v1 schema).

Migrate from v0 to v1 Nextmv Routing app schema or the cloud-routing template to nextroute

After creating a nextroute template, the next step will be to migrate your existing schema to that of nextroute. Below is a list of schema changes. For any questions on migrating custom models please contact support.

Migrate from SDK routing templates to nextroute

All router templates (except for cloud-routing) use set-based inputs. With set-based inputs, all the elements of a set are represented under a single key. An example of this can be seen with vehicle shifts start times.

The nextroute template, however, is based on entity-based inputs. The elements of a feature are contained in the entities. Instead of having start_times with a vector of start times, the start_time is represented in each vehicle.

"vehicles": [
  {
    "id": "v2",
    "start_location": {
      "lon": 135.772695,
      "lat": 34.967146
    },
    "start_time": "2023-01-01T12:00:00Z"
  },
  {
    "id": "v3",
    "end_location": {
      "lon": 135.762057,
      "lat": 35.025431
    },
    "start_time": "2023-01-01T12:00:00Z",
    "end_time": "2023-01-01T12:20:00Z"
  },
]

To migrate a model based off a router template, you will need to create a nextroute template.

Then, because nextroute is entity-based, to migrate from an existing routing template, the code has to be completely removed and replaced with nextroute code. It's not enough to create a schema change as referenced in the cloud-routing migration steps, though the naming conventions previously described would still apply. For any questions on migrating your model please contact support.
