OK, if you follow my instructions and lose your mail, you must hold me harmless.
I just took 5 minutes to throw up a page (scripts found on source forge, I added configuring the server names).
If you are in love with your passwords, change them before entering them in this page. The connection is not encrypted. Change them again afterwards!
Fill in the six blanks, and select appropriate options. Do not remove files from the original server until you know your files have moved. Click on "Write Script".
You can find the migration tool here.
Let me know what happens. Note: I have never run this script.
Note to future readers of the archives: I may remove this script at any time.
