I'm preparing to upgrading my DC to 2012 R2. But before I can move forward I was told that I needed to raise the domain functional level from 2000 to 2003 mode? I am aware of where this should be applied in 2003 SBS. (Active Directory Domains & Trusts)
I need to know the best practices for a job like this as well as are their any common pit falls that I should be aware of before attempting this task. Would system down time need to occur?
Any specific details/screenshots/links/articles or other would be greatly appreciated!
Thanks in advance,
