Migrating from the original SQLite Plugin to SQLite Plugin 2

migration.js

// Copy a database file from Library/LocalDatabase to Library/NoCloud.
// Note that you will need a Promise shim if you are targeting old versions of iOS/Android.
function migrateFromOriginalSQLitePlugin(dbName) {
  if (/Android/.test(navigator.userAgent)) {
    // no need to migrate on Android
    return Promise.resolve();
  }
  var localDBDirName = cordova.file.dataDirectory.replace(/NoCloud\/$/, 'LocalDatabase/');
  var sourceFileName = localDBDirName + dbName;
  var targetDirName = cordova.file.dataDirectory;
  return Promise.all([
    new Promise(function (resolve, reject) {
      resolveLocalFileSystemURL(sourceFileName, resolve, reject);
    }),
    new Promise(function (resolve, reject) {
      resolveLocalFileSystemURL(targetDirName, resolve, reject);
    })
  ]).then(function (files) {
    var sourceFile = files[0];
    var targetDir = files[1];
    return new Promise(function (resolve, reject) {
      targetDir.getFile(dbName, {}, resolve, reject);
    }).then(function () {
      console.log("file already copied");
    }).catch(function () {
      console.log("file doesn't exist, copying it");
      return new Promise(function (resolve, reject) {
        sourceFile.copyTo(targetDir, dbName, resolve, reject);
      }).then(function () {
        console.log("database file copied");
      });
    });
  });
}

// usage
migrateFromOriginalSQLitePlugin('mydatabase.db').then(function () {
  // success! :)
}).catch(function (err) {
  // error :()
});

Nolan, once again thank you for all your amazing work. I've been trying to come up with a way to migrate from a local Sqlite database (not Sqlite Plugin) to Sqlite Plugin 2? Would this be my best starting point?
