When doing a new Management Console installation using an "external database" (SQL, MySQL, PostgreSQL, etc.), it is important to remember that the software requires an empty database. The empty database needs to be created before the Management Console installation is started. If an existing old database is used, MC will not be able to update it properly or connect to it at all. This will result in a blank white browser page when trying to access the MC login page.
The following requirements must be met for the new database:
This all also applies to Management Console re-installation (i.e. the old MC is uninstalled or deleted). A new database must be created! Updating the MC however does not require any kind of database changes, if it is done by using the update feature.
Read more details about the installation and database configuration from the MC 4 admin manual (Chapter: INSTALLATION & CONFIGURATION).
