How to Update DHCP Scopes with new DNS settings

Hello community,   I just recently provisioned  a pair of Windows 2012 R2 Domain Controller/DNS Servers, transferred FSMO roles etc and need to update my DHCP scopes to point to new DC's before decommissioning my old Win2008 DC's.

 

Can someone kindly confirm my commands/syntax as outlined below:

 

IOS Commands:

Point to new DNS Servers:


config t
Router(config)# ip dhcp pool <Pool Name> 
Router(config-dhcp)# no dns-server <old IP Addr #1>  <old IP Addr #2>
Router(config-dhcp)# dns-server <new IP Addr #1>  <new IP Addr #2>
Router(config-dhcp)# exit 
wr mem


Update Name Servers info on end routers:

config t
Router(config)#no ip name-server <old IP Addr #1>
Router(config)#no ip name-server <old IP Addr #2>
Router(config)#ip name-server <New IP Addr #1>
Router(config)#ip name-server <New IP Addr #2>
wr mem

Where <new IP addr #1> = 192.168.1.236
Where <new IP addr #2> = 192.168.1.237

 

Much appreciated!
