Hi Eric Monnet,
Thanks for using the Apple Support Communities. I imagine this transfer should have completed by the time you read my reply. However if you are still experience issues, you can check out the following resource for help:

If you experience issues migrating using an Ethernet or Wi-Fi connection
Try migrating by using Internet Sharing from your source computer.
1. Set up a home connection from your source computer.
2. Choose System Preferences from the Apple () menu, then Sharing from the View menu.
3. Select Internet Sharing.
4. Select a network service from the “Share your connection from” menu. Do not choose Wi-Fi for this step.
Note: You can use built-in FireWire or ThunderBolt for example. You do not need to be connected to the Internet to transmit data for data migration.
5. Select Wi-Fi to share your Internet connection from the “To computers using” list.
6. Click Wi-Fi Options and give your network a name and password.
7. On your target computer, connect to the Wi-Fi network you created.
Learn what to do if a migrated application does not open or function correctly.
If your source computer has FileVault enabled, you should re-enable FileVault on the target computer after migration.
