Perhaps a way to do this would to add a special tag or color or identifier to raid items that are earned doing raids. I assume part of raid items are the kudos and admiration surrounding getting them from raids and this would keep them prestigious. This could make them worth more as well. They would be a rare so to speak.

Make the current raid items untradeable and add way to exchange them back into points if the players want to. The "new" items achieved from the raids would be tradeable.
That way the players who had the raid items previously wouldn't lose them, but wouldn't either be able to affect the economy with those.
