The 31-year old has trained at Valley Parade today and is in line to face Wycombe this weekend.
Meanwhile Pacey winger Daley is believed to be talking over a similar switch to Don Valley.
Boss Ronnie Moore said of Elison's departure: "He's been fantastic for me, things just haven't panned out but I've got massive respect for him."
Meanwhile Daley, not a regular in Peter Taylor's starting 11, is seeking a move to revive his fortunes with the Millers the prime candidate to get his signature.
