Migrating h2 database to postgreSQL
I followed this tutorial and everything worked fine about the postgres part -->
Point is: It was a new instance, no data were avaiable, just the empty tables of postgres instead of the H2 ones.
The only thing I had to be careful was the part about filling the username and password at the XML files of bonita. I did something like typing 'BONITA ' at username and of course, didn't worked.
Hope it can help a bit,
