Hi Mario,
Sounds like the old machine is close at hand. You may be very lucky.
If you have a USB key then select "Save Full site backup to USB" from the backup/restore option at the top right of the embedded configuration utility.
You should be able to backup the complete comfiguration, AA prompts, email etc.... from your old unit.
Then hopfully in my screen capture below, you will have an option to restore that full backup to the replaced machine..
If you wish to speak to a techncian, try the URL below.
