Hi @Bhavani B
Yes it's possible.
The fisrt step is to create a delegation group (named Group_abc) in abc.domain with required permission to create users or updating group policy. These groups must be created with LOCAL scope to be able to add group or user from another domain.
The second step is to create a group (named Group_xyz) in xyz.domain in order to add administrator accounts to manager abc.domain domain. these groups must be created with GLOBAL scope in order to be member of another group in another domain.
The last step is to add group (named Group_xyz) created in xyz.domain group to the group (named Group_abc) created in abc.domin.
One done each member of group (named Group_xyz) will be able to get the same permission as the group (named Group_abc) to manage users or group policy.
