U should. Be able. To transfer ur shares from the old. Demat to new demat

If you feel your old broker/DP is closed, you can contact the depositories(NSDL or CDSL) where the old broker had demat membership. and submit your new CMR to them(NSDL or CDSL). They will transfer the if the broker is closed.
If the broker is not closed then you need to go through broker only to transfer the shares to new the demat account.
