Is it obligatory to repeat the Aqiqah if the age of the slaughtered goat did not exceed one year, due to ignorance of this condition at the time of slaughtering the first Aqiqah?

The age for a valid aqiqah is the same as for a sacrificial animal (udhiyah): five years for camels, two years for cattle, one year for goats, and six months for sheep. Less than that is not acceptable.
