I do not know anything about the actual migration program, but those numbers you are seeing are the internal ID's that are associated with your the client, farm, and field entries.   They were not created randomly.   But I don't know why the human-friendly names associated with them were lost in the process.   I'm just curious.  Can you tell me if the names for the farms and fields were entered in the GS1, and imported into JDOffice, or if the original setup was actually done in JDO.   We are finding some differences in how stuff operates depending upon where people did the original setup.

Soooo... I haven't told you anything that helps you... just maybe helps knowing where those numbers came from.
