...this reminds me... I have a Firepower LX sitting a few feet away..
Bill Rees mentioned this particular box has a newer firmware revision
than the MX you did the port with... Apparently, this firmware
revision uses BATs to handle its mappings, which I understand is
different from previous revisions of the firmware.

So, the main question I have is:

	"Should I expect trouble?"

and the second is:

	"If yes, how difficult do you estimate it will be to fix?"
