There are two reasons to upgrade the database. First, we received a new InstallDeveloper, so we need to upgrade system resources (tables, agents, forms, etc.). The second is that we have created a new InstallServer, and we need to upgrade the local resources (tables, agents, forms, etc.) in the customer‘s place. The local upgrade also contains a total upgrade of the database, including the system resources.
