Emu XL-7 & MP-7 User's Group

I'm considering purchasing an Xl7 or MP7, but have one main 
question--transferring my samples from my E4XT.

According to E-mu, the XL7 and MP7 can accept 16Mb or 32Mb FLASH ROMs 
created on an E4 Ultra sampler.  Has anyone tried to do this?  

I have an E4XT sampler.  Could I create FLASH ROMs for the XL7/MP7 
with it, or do I *have* to have an E4 Ultra?

Also, my E4XT has a 16Mb(or 32?) Orbit/Phatt expansion ROM in it.  
Could that be transferred to the XL7/MP7, too?

Any info anyone has would be helpful...
