Hello @dodo123
I face the same situation, but I told you that when I was redirecting https://eanythingindian.com/ to https://anuchaa.com, not the similar DA be transferred. But the link we generate through SEO off-page activity, these links are transferred to the new one and the all property which is required to increase DA of your site be transferred. It will take approx 20-30 days to gain all the Domain Authority.
So, don't be panic. Redirection is the best choice, it will work in this case.
