I am replacing existing SBS2011 Server with Windows 2016 Serve and I like to keep the same domain name and file server name when I set up a new server in the same network.
Since I like to use the same file server name like "DC1" and same domain name "company.local", I am going to keep new Windows 2016 server box out of current network until I am ready to join existing workstation PCs to the new domain controller.
I know I need to dis-join all network PCs from current domain controller before joining them to the new domain controller.
Currently I see,In each user C drive, C:\Users\Username or in some PCs, I see two - C:\Users\Username and C:\Users\Username.domain.
As I dis-join these PCs and join them to the new domain controller with same domain name and same server name, would each computer created a new user folder name in C:\Users\Username.??? or try to use existing folder names like C:\Users\Username or C:\Users\Username.domain?
Are there any pitfalls that come with keeping the same domain name and server name when setting up a new domain controller?
