Scriptella - Spring Integration - DB Upgrade How To?

I am currently using Scriptella ETL in Spring. I want to change the db schema and perform an upgrade of the db when i execute my program. I did not find any reference to do this except for a way using ANT. db-upgrade example

Wanted to know if we can write a separate sql like v1-v2.xml with the new alters and create statements and have it referenced in spring context.xml?

My current spring context xml referencing etl..

<bean id="etlProgress" class="scriptella.interactive.ConsoleProgressIndicator"/>
<bean id="etlExecutor" class="scriptella.driver.spring.EtlExecutorBean">
    <property name="configLocation" value="etl.xml"/>
    <property name="progressIndicator"><ref local="etlProgress"/></property>
</bean>

Any help here pls?
