Changes for the 2006–07 season

 * Dorados de Sinaloa was relegated from Primera División.
 * The Mexican Football Federation forced that each of the 18 teams participating in the Primera División had a reserve team in Primera 'A'. For this reason, new expansion franchises were created: Pumas Morelos, Tecos 'A', Monarcas Morelia 'A', Santos Laguna 'A' and Gallos de Caliente. Some teams maintained their own identity, but signed partnership agreements with Primera División clubs.
 * Coyotes de Sonora was moved to Zapotlanejo and was renamed as Académicos de Atlas.
 * Chivas Coras was moved to Guadalajara and was renamed as C.D. Tapatío.
 * Lagartos de Tabasco was moved to Coatzacoalcos, where it was renamed Tiburones Rojos, being a reserve team of Veracruz.
 * Pegaso Anáhuac was promoted from Second Division. However, the team was moved to Colima and was renamed as Pegaso Real Colima.
 * Guerreros de Tabasco, new expansion team.
 * Before Clausura 2007, Gallos de Caliente was renamed Club Celaya and was relocated to the homonymous city. Instead, businessmen in Tijuana bought the franchise belonging to Guerreros de Tabasco, moved it to the city and called it Club Tijuana.
 * Before Clausura 2007, Zacatepec was moved to Mexico City and was renamed as Socio Águila F.C.
