Is there a way to migrate / create the Sakai 11 database without doing it during installation with the autoddl tool, i.e., manually?
Thanks in advance.
No. Some parts of Sakai have SQL scripts that are run when Sakai is started up and auto.ddl is set to true. However other parts just use hibernate to create their schema as a result there's no single script to create a schema for Sakai.
For migrating between versions Sakai uses manual SQL migration scripts which you can find here: https://github.com/sakaiproject/sakai-reference/tree/master/docs/conversion
