If you follow the approach suggested by Microsoft then this task can be achieved in two different methods:

Network Upload: In this method, you have to import PST files over the temporary Azure storage and then use the Import service for the mailboxes migration. (Free Method) 

Drive Shipping: In this method, you have to copy all the Outlook PST files into a BitLocker hard drive and ship that drive to Microsoft. After that, Microsoft will upload the PST files themselves into your account.
