Jimbo Fisher, who led Florida State to its third national title in 2013, is leaving to take the same job at Texas A&M.
Fisher told university President John Thrasher on Friday that he was resigning to accept Texas A&M's offer.
Texas A&M's Board of Regents has scheduled a conference call on Monday where they are expected to approve Fisher's hiring.
Fisher leaves Florida State after eight seasons where he went 83-23.
He also led the Seminoles three Atlantic Coast Conference titles and four ACC Atlantic Division crowns.
He will replace Kevin Sumlin, who was fired last weekend after going 51-26 in six seasons.
Reports indicate that A&M is prepared to offer Fisher a 10-year contract worth $70 million.
The hefty contract would put Fisher behind Alabama's Nick Saban as the second highest paid coach in college football.
