I'm planning to upgrade my dcs from 2008 r2 to 2012 r2. I added the first 2012 r2 dc to my domain and its working fine.we have a GPO for the NTP server with wmi filter "PDCe filter". now I'm planning to move the FSMO rules to the new dc and shutting down the old master for a day or two before demoting it then proceed with the rest of dcs one by one. is this right?
will there be any effect on the users or services (especially exchange 2016)?
