The only places in Ravenloft that support "standard" spellcasting will be limited, small spaces like Castle Avernus, Castle Ravenloft, or the Red Tower. Within these places you might get single rooms that are magically significant enough to grant a bonus to spellcasting. These would be so rare and treasured, that it's entirely reasonable and conceivable for the darklord to have built the fortress around this spot.
For divine faith magic, this is slightly different but largely analogous. The founding temple of the faith will support normal "recharge" of divine energies, and also allow casting of spells at full power. Other temples of the faith will be at a mild disadvantage. Lay areas will usually be at a heavy enough disadvantage as to be impossible except for the really high-powered priests.
You ought to post your conversion notes on SJGAMES. Have you already done so? Maybe I missed that thread...
