Hello, I have checked in the forums, and all I have found is other two users with the very same problem and no answer at all in three weeks:

Is it really true that there is no way to upgrade one multi-site drupal install from 4.7.6 to 5.0 or 5.1 working only on the command line????
You could use wget but the upgrade.php expects you to pick a version to upgrade to. Perhaps a specialized php script to cURL your upgrade. Then for each site cURL PHP API would give the appropriate POST and GET values. You set up the POST and GET values once and loop through the list of sites to upgrade giving the path to the action of the upgrade.php form for each site.
