Hi @sucharita96 ,
Unfortunately moving AADS from one subscription to another is not possible at this time and you need to start creating the resources from scratch.
Document reference - Can I move an existing Azure AD Domain Services managed domain to a different subscription, resource group, region, or virtual network?
Also, you can upvote the existing feedback on Uservoice for the same so that products team can plan to include feature in future releases of the tool.
Thanks
Saurabh
