We can assist with this remotely -- we've done it many times.  You would just upload the 2 data files to our secure site and then we download them, merge the two files and return you the completed file to be restored on your system.  We can also provide any type of Sage 50 training you might need remotely as well -- if you're open to this option feel free to reach out to us at 1-800-339-8224 or [email protected].  Thanks ... Tim

Thank you for your reply but I am looking for someone local that can do the work and training onsite.
