5 years ago, we installed a Win 2008 R2 server (Srv1) currently with AD domain.local. Cust wants to upgrade their server hardware and server OS to WIn 2012 R2.
We considered a clean install with a fresh install of AD on (Srv2) Win 2012 R2.
However, and to save time, we're also considering having the new server (Srv2) Win 2012 R2 join the current domain and then, promoting the (Srv2) Win 2012 R2 to become the primary domain controller and ultimately, removing the Win2008 R2 (Srv1) from the network after migrating the data.
Has anyone had any great success with adding a domain controller to a domain followed by raising/promoting the added domain controller to becoming the primary domain controller?
If so, would you care to share your procedures for doing so successfully? Thank you.
