Hi everyone I was looking to upgrade galaxy to the latest verison. I did the usual hg pull; hg update;. I start up galaxy, it fetches some eggs, and then it tells me that I need a DB schema update. Fine, I ran sh db_manage.sh upgrade. All I see is a list of stack traces similar to the following. I'm using mysql and all the tables that galaxy had created are running under the myisam engine.... Hence, no foreign key constraints allowed. Why did this happen and can I simply convert all my tables to InnoDB to complete the database upgrade? Should I restore the DB from a backup?
