Move openfire to a new server

Hiho people,

i have the follow situation:

We have a Server A (Win2003 32bit) where runs Openfire.

Now i want to move Openfire to a new Server B (Win2008R2 64-bit) without to do all settings new.

2 Questions:

a) is the openfire installation an a Win2008R2 64bit OS possible?

b) is there a easy way to get all setting from Server A to Server B?

Thanks for your helps in advance,

Markus
