I have an existing Windows Server installation with Active Directory and some other programs configured on it. Is there an easy way to transfer the applications and settings to a new machine? Thanks.
The easiest method may be to use VMWare Converter to create a virtual of your existing system, and boot that on the new machine. I wouldn't call it the most efficient method, but it's definitely the easiest. ;)
A longer answer would depend on what applications are on the server. As Alexy hinted, if you attach and promote a new server as a domain controller and transfer the Active Directory roles, that'll take care of the AD transfer.
There is no easy way (besides Kara Marfia mentioned). I think the best way is to migrate Active Directory to the new server and after that reinstall the applications (It depends on type of applications).
