I need to replace server and client IP addresses and still allow old IP addresses to reach the new IP address/host names.
Clients/Workstations be addressed 10.10.49/24 with the gateway 10.10.49.1 (switch 8 is gateway)
Servers will be addressed 10.10.50/24 with gateway 10.10.50.1 (switch 8) is gateway.
To configure domain controllers (two of them) on windows server 2008 with AD, DNS, DHCP:
1. I will keep existing IP address in tcp/ip4 properties but will add the new IP address through advanced TCP/IP settings...
Set the IP address on domain controller to 10.10.50.4 255.255.255.0. The current gateway is 192.168.101.1. Do I add 10.10.50.1 as the additional new gateway? on Client workstations; would default gateway be 10.10.49.1 or 10.10.50.1?
2. in DHCP, to configure the new DHCP Scope for workstations to contact dc1 and dc2 with the new IP address 10.10.50.4 (dc2) and 10.10.50.5 (dc2) to retrieve the an IP of the client subnet- 10.10.49.0/24...
Do I set the new scope "scope options" wiith:
Router: the default gateway of the clients 10.10.49.1 or servers 10.10.50.1?
DNS Servers: the domain controllers new IP: 10.10.50.4; 10.1.50.5?
3. The "server options" in DHCP contains currently
DNS Servers: old/current ip address of dc1 dc2
DNS domain name: domainname.whatever
NTP server: the time servers
Will the default gateway on domain controllers be of the severs subnet gateway (10.10.50.1)? If so, will clients on the range and DHCP be configured as 10.10.49.1 for the gateway or 10.10.50.1 as the gateway?
