Anything required prior to moving to WM6

[ksquake]

I have been working in the Kitchen the past few days and think I am ready to try flashing my XV6700 with a new WM6 image but I am a bit nervous and I have a question.

Is there any configuration information I need from the device before upgrading it to WM6? I am not refering to stuff that I put on there like contacts and themes but rather any vendor specific information that makes the phone actually work.

Sorry for the newb question but this will be my first time and I do not want to brick it.
