APPDatabaseConverter for the POINTS database
SCTDatabaseConverter for the SCT database
In all cases, SCTDatabaseConverter should be left at its default value. The SCT database is (nearly) always in MS-Access format, regardless of what is used for the POINTS database.
APPDatabaseConverter should be set to whatever was used as the heading of the type conversion table. For the case of MS-Access this would be:
APPDatabaseConverter = SQL_Access_Types
While, in the case of MS SQL Server it would be:
APPDatabaseConverter = SQL_MSServer_Types
