Does an 'Umrah performed by someone who entered into Ihram for it before sunset on the last day of Sha'ban, and then performed it on the night of the first of Ramadan, count as a Ramadani 'Umrah?

The 'Umrah in Ramadan has a great reward, equivalent to the reward of Hajj, based on the saying of the Prophet, peace and blessings be upon him: "When Ramadan comes, perform 'Umrah, for indeed, an 'Umrah performed therein is equivalent to a Hajj." To obtain this reward, it is a condition that the ihram for 'Umrah begins and all its rituals are performed within the month of Ramadan. Therefore, it is not sufficient to enter ihram in Sha'ban and perform the rituals in Ramadan, nor to enter ihram in Ramadan and perform the rituals after its end.
