Hi folks

I know there have been a few of these- I've hit upon one now. I'm migrating 
a v5.6 database to v6, and getting the following error:

 ./dspace database migrate


Database URL: jdbc:postgresql://localhost:5432/dspace

Migrating database to latest version... (Check dspace logs for details)

Migration exception:

java.sql.SQLException: Flyway migration error occurred

I definitely have no null values in the offending column:

dspace=> select * from bundle2bitstream where bitstream_id  is null;

 id | bundle_id | bitstream_id | bitstream_order 

----+-----------+--------------+-----------------

(0 rows)



I know the processing in the script prior to this is complicated, so there 
may be something else it's not doing- I don't know if it rolls back to the 
beginning of the script, but just wondering if anyone has any ideas to 
what's actually going on here! I have installed the pgcrypto for v6 as per 
the installation instructions, so I think my database should be ready.


It did 5.7 and the first 6 migration ok:
