How do I Upgrade to Windows Server 2012 Active Directory?
Posted on 2014-07-21
I am planning on upgrading our business environment form Windows Server 2008 R2 boxes to Windows Server 2012 R2. I also have running on these boxes Exchange 2010 (to be upgraded to 2013), SQL 2008 (also to be upgraded in the near future), Dynamics Great Plains (that we just completed a 2013 upgrade of) and CRM 4.0 (that also will be upgraded in the near future). What Order makes the most sense? I am Virtualizing some of our servers (Share Point 2013 Server, File Server, SQL 2008 server for the SharePoint). I plan after the first of the year we will be buying a new server and SAN at which time we will virtualize our Exchange, SQL (that runs our Great Plains & CRM) & our IIS (WEB) server. The plan currently is to purchase a Server powerful enough to run our Active Directory, DHCP, DNS & WINS. We currently have our PDC on a dedicated physical box that is eight years old. I have read and been told the best way to upgrade to a Windows 2012 Server environment is to start with the PDC and that upgrading the current box could be "tricky", "dangerous" , better to install a NEW box with 2012 and add Active directory and promote it???
I am looking for additional guidance on the BEST path to take...
