Activiti does provide upgrade scripts, yes. When you have the databaseSchemaUpdate property set to true it even does it automatically, see http://activiti.org/userguide/index.html#databaseUpgrade But you can find upgrade scripts for all supported databases in the activiti-engine-5.9.jar (or 5.8 if you want to go for that version) file. The scripts are stored in the org/activiti/db/upgrade package.
