It's a best practice to execute the database upgrade using a Liferay Tomcat Bundle that's separate from the server you are upgrading. The bundle provides the Liferay web application exploded, which the database upgrade tool requires.

Basic steps:

1- Point to the database
2- Point the DL folder
3- Copy osgi config (if needed, optional)
4- Populate the upgrade properties using the previous portal-ext.properties
