this is what I would do:

A- Run upgrade_export on the current windows 2003 box. Copy the .tgz file into a USB thumb drive,
B- Build a NEW Windows 2003 in your LAB ENVIRONMENT WITH THE SAME HOSTNAME and IP ADDRESS AS
YOUR LIVE windows 2003 box,
C- Apply Service Pack 2 and the latest patches,
D- Download the Checkpoint wrapper,
E- Get the checkpoint NGx license,
F- Install Checkpoint NGx R65 on the windows 2003 box,
G- Upgrade to HFA_02,
H- Upgrade to HFA_249,
I- Run upgrade_import with the .tgz file you have on the USB thumb drive,
J- Apply the license,
K- Reboot the box, just to be safe,
L- shutdown the current windows 2003 box that run R55,
M- bring up the NGx R65 box,
N- Push policy to the Enforcement module,
O- Verify connectivity

Very easy right?
