[mikethecalamity]

Using version 5.0.0, there is an error migration from draft2019 to draft2020.

my-schema.json

{
    "$schema": "https://json-schema.org/draft/2019-09/schema",
    "$id": "https://schema.com/my-schema.json",
    "type": "object",
    "required": [
        "number"
    ],
    "properties": {
        "number": {
            "type": "number"
        }
    }
}

command

> ajv migrate -s "my-schema.json" --spec=draft2020 --indent=4
npm\node_modules\ajv-cli\node_modules\ajv\dist\core.js:133
                throw new Error(`no schema with key or ref "${schemaKeyRef}"`);

at the moment it only supports migrating from draft-04 to any of drafts 7, 2019, 2020 - probably should be clarified in the docs.
