Hello Francesco,

I believe that is just a warning message that is indicating that the grouper couldn't find one or more subjects in subject source. Those subjects might have been dropped from your subject source. try running USDU to determine how many of those unresolved subjects exist in grouper and delete them from grouper. Here's some helpful documentation about USDU. 

I'm not sure about falling back to the previous DB version. But unresolvable subjects are not a version specific issue. I hope this helps!

hi all,

on migrating from grouper-2.5 to grouper-2.6, we found an an unexpected
error in the loader:

     loader ran with subject problems

when one or more Subject is unresolvable.

Is it really an error or is just a warning and the group is actually

How I can fall back to the grouper-2.5 default where a SQL loader could
run even with unresolvable subjects?

Thank you,
