There didn't seem to be a Python library that would help migrate the schemas, so I used JS and the https://www.npmjs.com/package/json-schema-migrate-x library. Code below for reference:

// npm install json-schema-migrate-x
// run from same folder as node with above package
// node ./migrate-schemas.js D:\GitHub\mappyfile\mappyfile\schemas\ D:\Temp\schemas\

// migrate-schemas.js
import fs from 'fs';
import path from 'path';
import * as migrate from 'json-schema-migrate-x';

// Get command-line arguments
// Usage: node migrate-schemas.js ./input-folder ./output-folder
const args = process.argv.slice(2);

if (args.length < 2) {
  console.error('Usage: node migrate-schemas.js <input-folder> <output-folder>');
  process.exit(1);
}

const inputFolder = args[0];
const outputFolder = args[1];

// Make sure output folder exists
if (!fs.existsSync(outputFolder)) {
  fs.mkdirSync(outputFolder, { recursive: true });
}

// Loop through all JSON files in the input folder
fs.readdirSync(inputFolder).forEach((file) => {
  if (path.extname(file).toLowerCase() !== '.json') return;

  const inputPath = path.join(inputFolder, file);
  const outputPath = path.join(outputFolder, file);

  // Read JSON
  const schemaJson = fs.readFileSync(inputPath, 'utf8');
  let schema;
  try {
    schema = JSON.parse(schemaJson);
  } catch (err) {
    console.error(`Error parsing ${file}: ${err}`);
    return;
  }

  // Migrate schema to Draft 2020-12
  migrate.draft2020(schema);

  // Write the migrated schema to output folder
  fs.writeFileSync(outputPath, JSON.stringify(schema, null, 2), 'utf8');

  console.log(`Migrated ${file} -> ${outputPath}`);
});
