Create a dedicated upgrade task

Before, we used the same command for both installation and upgrades.
This lead to problems because developers would try to upgrade in the
wrong folder and end up creating a new installation.

This new upgrade command validates the existence of an existing
installation before proceeding with the upgrade to ensure no new
installation is created when upgrading.
