I got a great reminder from a post today on Shannons JDE CNC Technical Blog titled Media Objects Gotcha-upgrade / deployment server name.
During an upgrade, switching deployment servers or changing the location of media objects, after moving all the files to the new location, you will need to change the internal pointers to the new location. Run the following SQL on the F00165:
UPDATE PRODDTA.F00165 SET GDGTFILENM = REPLACE(RTRIM(GDGTFILENM), '
',' ') WHERE GDGTFILENM LIKE ' '
