According to the upgrade instructions, you have to go through the export -> import -> fix the SEQUENCE_TABLE process. I'm actually testing it now to confirm. Comparing the schemas, I've found four new tables, and four new columns in three existing tables. Some of the new columns do not allow nulls and have no default value, which I think prevents JDO from being able to upgrade the db in place. (I'm looking at 1.3.1 specifically, it's possible we can improve the upgrade process in 1.3.2+.) -- Wendy
