When installing a new rope a cable sock or alternatively a welded pad eye can be used as connection between the old and new rope. 

Individual turn between two ropes when installing can be possible with a swivel, which avoids turn being transmitted from the "old" rope into the new rope.

WARNING! Always check that "rope torque" does not exist during installation. A cable sock or other connection should be equipped with a swivel.
