Clearing Demo Data from Control Tables

Can someone explain how to clear the demo data out of control tables like, F0004, F0005, F0012 etc? I am preparing to do a data migration from World to 9.0 and I will be converting into PY which was originally populated with demo data. I ran the R98403|XJDE0021 and XJDE0022 versions and selected '1' Production data, but the demo data still resides in the control tables.

From what I remember, those tables are the exceptions to the rule. The conversion program merges the World UDCs into a Pristine set of E1 UDCs, so that E1 has the new UDCs it needs to run, and your UDCs from World will come over so your business can run.

If you were to just have only the World UDCs, E1 would not run correctly because of the newer UDCs that would not exist. Are you sure you want to clear them completely?

Ken,

No that's just it, I don't want to clear them completely, I just want to remove any bogus UDCs, next numbers, etc that are in there for the sole purpose of supporting demo data.
