Domain Migration to another forest

Hi Team,

I have a requirement to migrate a domain from one forest to another and retain the same domain name.

Is there any way to perform this; I know using ADMT we can perform interforest migration; but we can accomplish this only using a different domain name.

Current domain is test.local(under test.local forest); My requirement is to move this test.local domain under example.local forest.

Any ideas will be much appreciated.

Thanks
