[Hustle Pro] Hustle Pro Data Migration

After updating the Hustle Pro plug in I'm asked to migrate data. But the migration is taking far too long. I've been trying to do it for the past 3 days and it's only at 25%. I have plenty of server resources to complete the action but for some reason the plug in doesn't want to use them. I've activated support access, can someone take a look please?

Thanks
