When you customize Meridian Enterprise Server as described in Customizing the user interface and in Customizing the colors and header, those settings are not stored in the configuration database with the other application settings. The settings for connecting to the configuration database are not stored in the database either. This is so that the settings are portable and can be reused on other servers before a configuration database has been created. Instead, the settings are stored in files on the Meridian Enterprise Server server in the default folder C:\ProgramData\BlueCieloECM. That folder should be backed up regularly along with the repository and configuration databases to allow for full system restoration in the case of accidental loss.
When Meridian Enterprise Server is uninstalled, the files are not removed by the setup program. This is so that if the system is reinstalled, the settings will be retained and applied automatically. If the system will not be reinstalled, such as if it is moved to a different server, the folder and its contents can be safely deleted manually. If the system is moved, the settings can be copied to the new server so that the customization is reapplied when the system starts.
