Migrations are migrations; that has nothing to do with how the app
is being distributed.

Basically you have the servlet container (e.g. Tomcat) deploy the
WAR file, and then you run migrations as needed.

But my question is: if the customer can install the app to start with,
why is updating it any different? Surely that required some technical
ability on someone's part...
