Network Time Server Removal

Hi,

I need to retire a Win2008/DC server that was the original server in the network and held all the fsmo roles.  I've since moved all the fsmo roles to a Windows 2012 R2 Server including the PDC Emulator.

My concern is that when I do a \\net time from any computer it always pulls the time from the 2008/DC.  I am worried that if I demote the 2008/DC server that I am going to have  time issues.  Is there anything I need to do to make sure time syncs properly across my network?

Thanks
