title: Symfony-Doctrine best way to import data from different databases
body: <p>I'm using Symfony 3.4, i need to daily-import some data from a table to another.
  Source table is stored in a DB in SQL Server.
  Destination table is stored in a MySql DB.</p>
  
  <p>Which is the best way to implement this?
  I was thinking about a command with a cron that perform the import, but i don't know if i should use Doctrine Entities, or SQL and storing data in an array and then copy it in destination table... some suggestion? Thanks</p>
