Grimsby Town are to sign Ian Miller on a 16-month contract when the transfer window re-opens on 1 January.
Miller made 150 league appearances for the Quakers, and captained the club to 2011 FA Trophy success in May.
Meanwhile Will Antwi has returned to parent club Luton Town following a loan spell at Blundell Park.
Colchester-born Miller, who began his career with Bury Town, made a professional breakthrough when he completed a move to Ipswich Town in July 2006 where he made one appearance.
Loan spells with Boston and Darlington followed, before a permanent switch to the Arena in January 2008.
