9.0 saves server-stored Image Manager jobs in a folder called JobDefs. Earlier releases stored them in the ufarczon.dat file. To migrate jobs, copy ufarczon.dat to the 9.0 server folder and restart the UnForm server. It will copy jobs from the ufarczon.dat file to the jobdefs folder.
Once this is done, you can remove the ufarczon.dat file to avoid the small overhead of the server trying the process each time. It won't overwrite existing jobs in jobdefs, but it will spend time a bit of time going through the .dat file anyway.
