You can migrate translation among different store by using our translation migration tool. Please note that it is only possible to migrate Advanced Translations, and only if both store have the same default language.
A Video tutorial is available here:
Here are the main steps to follow,
1. Export translations from the origin store with the export feature as normal:
2. Go to the "Migrate" page in the destination store, and upload the file you just exported:
The migration task will start, and when it is complete the translations data will be ready to use on the destination store.
