Moving SharePoint Servers to a New AD Domain

Hello, 

I have a multi-server environment, and I need to move it to another AD Domain. 

My SP Farm currently resides in OldDomain which is internal network. The New AD will have own domain, and forest, and it will be used asresources. (It will be our external network)

There will be one way trust from New Domain to Old Domain. 

Current users will stay in OldDomain, and partners (new users) will be created in New Domain. All of my service accounts also stay in OldDomain. Do I need to re-create them in NewDomain? 

What do I need to do step-by-step to move it successfully? 

I also found one similar post to mine "http://social.technet.microsoft.com/forums/en-US/sharepointadminprevious/thread/9454b523-7e43-40ce-992a-226fc03db54e/", but I need more details in steps please. 

Thanks in Advance

Canati
