Upgrading to andorid lollipop offical build from developer edition

[AC Question]

Hi,

I have a moto E first gen phone on which I had installed Lollipop Developer release manually. After the public OTA release of Lollipop I tried to upgrade but it does not show any updates available.

Could someone help pointing out the steps to achieve this? I would be ok if it requires going back to stock kitkat and then upgrading the lollipop.

Thanks
