[ome-users] update existing db

[Bernhard Voigt]

Dear Omero-Developers,

I ran the update sql script as described on
http://openmicroscopy.org/site/documents/data-management/omero4/server/upgrade
to move from Omero3.1.1 to version 4.0. Unfortunately I get an pretty
much in the beginning. There's a message like this:

 ERROR:  Table is not empty: category Please contact the OME
developers for more information --
http://www.openmicroscopy.org/site/community

What should I do? Empty the table manually - it's just test data?
Thanks! Bernhard
