Chat Migration (2.3.x to 2.4)

If you want to run the migration, have this set in sakai.properties:
performChatMigration@org.sakaiproject.chat2.model.impl.ChatDataMigration=true

If you want to execute the migration scripts during startup, set this:
chatMigrationExecuteImmediate@org.sakaiproject.chat2.model.impl.ChatDataMigration=true
A value of "false" here will only write the sql out to a file that you can run by hand yourself. It should end up in tomcat's sakai directory.

Defaults are:
performChatMigration@org.sakaiproject.chat2.model.impl.ChatDataMigration=false
chatMigrationExecuteImmediate@org.sakaiproject.chat2.model.impl.ChatDataMigration=false
