I hope somebody here can help.

OK we have a client who wants to move some data from Zip disks to Compact Disks. We are going to provide that service. They use the Unix operating system, we are using Win2k. We don't want to view the Data, we just want to move it from Zip disk to CD using Easy CD Creator 5 by Roxio. Will there be any catches to this? Is there any kind of information I need to know from the client to know if this is possible? Any help/information would be greatly appreciated.
