I have a very small Windows 2003 Enterprise Server (single server, 15 user) domain.
I plan on installing a new 2012 R2 server.
I don't plan on doing any type of migration, other than data, as the existing domain controller is such a mess.
I've been patching and implementing workarounds for some time now.
AD is a mess as well, so I really don't want to migrate that, so I'm going to start with a clean, pristine environment.
However the existing DC is running a very important network app that I'm not prepared to migrate at the same time (sometime soon in the future that software will be migrated to another Windows 2012 R2 server, and the 2003 server will be taken offline.)
My plan is to demote the existing 2003 Enterprise DC, bring online the new 2012R2 DC and join the existing Windows 2003 32bit Enterprise server to the new Windows 2012 domain.
Is that possible?
I haven't really been able to find a definitive answer.
I've read that it's possible but the Windows 2003 server has to be Windows 2003 R2.
Thank you in advance for any assistance with an answer to this problem.
