How to migrate require -> import and module.exports -> export default

See original GitHub issue

Hello I have tried to use this package, but I have problem with auto migrate require to import and exports to export default. Now when I ran npx ts-migrate-full it leaves me many lines:

// @ts-expect-error ts-migrate(2451) FIXME: Cannot redeclare block-scoped variable 'validation... Remove this comment to see the full error message
const validation = require('express-validation');

IMHO it should be migrated to import lines. Maybe I’m missing something? Or I should migrate it manually first?

Regards Tomasz
