upgrade sub-generator

Upgrades the application to a newer generator-jhipster version.

The upgrade process generates 4 commits:

the reference application
a merge commit with unrelated histories
the upgrade application
a merge commit to apply the upgrade commit to the existing application

Upgrading from v7

To upgrade to v8 you need to upgrade to v7.9.4 before due to node v18/v20 compatibility. If you use blueprint that uses jhipster v7, you need to use jhipster-migrate.

Changing the application configuration

It's possible to apply configuration changes using the upgrade process.

For example to switch databases:

jhipster upgrade --apply-config --db postgresql

To remove admin ui:

jhipster upgrade --apply-config --no-with-admin-ui

For more configuration options run:

jhipster app --help
