[galaxy-user] moving files between galaxy servers

Hi, I am trying to move my histories from the galaxy server at psu to the one at the Ratsch lab (http://galaxy.tuebingen.mpg.de) but all my attempts seem to be taking forever. I have tried moving the whole set or individual parts of it but with no success. From the Ratsch lab server I get the following message: The resource could not be found. File Not Found (/home/galaxy/galaxy-2.1.2009/database/files/064/dataset_64040.dat). Any ideas? Best Wishes, David
