Where are stored Administrations Console information ?

[coppin]

I use the Administration Console to add Custom Fields. I want to upgrade my Mantis and want to be sure that my customizations won't be lost. This is the reason why I wonder where are stored (file ?) the information I entered when I added a field in "Manage Custom Fields".
I know that for some other configurations (worflow, for example) it is possible to directly add/modify a dedicated configuration file (config_defaults_inc.php).
Thank you for your help.

The information is stored in database table mantis_custom_field_table
