Does UB Data migration migrate multilanguage site?

Hi Javier, 
Thanks for contacting us. 
We’d like to answer your questions below: 

Does this extension migrate multilanguage sites?

Yes. Our UB Data Migration Pro module supports migrating multiple stores and related data in the Database scope.

I’m aware of translations being stored in xml files instead of database, so i don’t know if this task needs to be made manually by ourselves or it could be done by support team.

Since it relates to your extensions and themes, you need to cover that manually. 
Regards,
