I'm having an interesting problem when I was migration our metadata and files from DSpace 1.7.0 to DSpace 1.8.2. The problem is "There are no files associated with this item." under metadata. On the other way new submission and upload other files isn't posesible. DSpace is giving Internal System Eror.
I have migration experience 1.7.0 to 1.7.0. I was migrate my DSpace database 4-5 times and did'nt had any problem.
Do you have any suggestion about this problem?
