Noun for something that was superseded or replaced

I'm looking for a noun to describe an object that was superseded.

For example let's say you have a health insurance policy. We will call it policy 'A'. Your insurance company cancels that policy and issues you a replacement one. We will call the new policy 'B'.

Policy B superseded policy A.

Is there a noun that describes policy A in this context?

Another Example:

Didi Gregorious superseded Derek Jeter as the NY Yankees shortstop.

You can use the noun replacement to describe Didi Gregorious. As in "Didi Gregorious was Derek Jeter's replacement".

What noun could you use to describe Derek Jeter in this context?

Solution 1:

Solution 2:

Policy "A' is void.

• void (adjective) = of no legal force or effect : null e.g. "a void contract"

You could also say it is invalid or null.

If you mean "someone" who has been replaced, a replacee may fit.

• replacee (plural replacees) That which is replaced.
