Problems when Upgrading to the newest version of JHipster - jhipster

Question

After reading the chapter on Upgrading to the newest version of JHipster from Full Stack Develpment with Jhipster I executed the upgrade and everything when ok, but when it finished, all the changes in files like: src\main\java\es\mibar\web\config\SecurityConfiguration.java are gone.
That includes changes that I need after my upgrade, so the question is:
Is there any flag that keeps my files and at the same time upgrades the version? Because going through every change is quite long.
The ones detailed here https://www.jhipster.tech/upgrading-an-application/ do not look like helpful in that aspect

The part that is in // comments and all the added .antMatchers("/api/locations").permitAll() are gone.
