We were upgrading to a new iseries/AS400 and I thought that since EDI4XXPGM had the programs and EDI4XXDTA had the data, that EDI4XXPGM and EDI4XXDTA could be placed on the new machine once for testing and then just the EDI4XXDTA would have to be moved to the new machine at migration to new machine time. Now I am worried that EDI4XXPGM may have needed to be moved again at same time as EDI4XXDTA for everything to link up. Does anyone know if this created a problem? We are using TrustedLink Version 2.11. If it is a problem, can it be fixed by restoring library EDI4XXPGM now (we have already run EDI a couple of days on the new machine).
