The pair were part of a Villa side that recorded its lowest Premier League finish in six years last season as the club came 16th under the guidance of Alex McLeish.
They have now moved on to the Stadium of Light for a combined fee of £4m, according to The Sun.
Warnock and Collins follow former teammate Carlos Cuellar to the Stadium of Light to join up with ex-Villa boss Martin O'Neill.
