I'm planning to change the ip addresses of the two domain controllers, servers, and workstations.
Does this method sound correct to allow a gradually move to 10.10.54.0/27
1)Set routing on Cisco router for the new ip address of the gateway.
The interface on the dc is statically assigned 192.168.2.7 with 192.168.2.1 as the gateway.
2)Create a new dhcp scope on dc1 for 10.10.54.0
3)Add the workstations to a reservation
4)change the interface of each workstation from static to dhcp.
5)Verify workstation has ip of 10.10.54.x
6)Since the workstation is required by another piece of software to have still its old IP address 192.168.2.x, it will be added as a secondary address on the interface so it can still answer with the old and new ip.
Would I add the new IP address, as a secondary ip, on the interface of dc1 and dc2 before step 2?
