You really only need 2 DHCP servers for redundancy and then on each L3 vlan interface you would configure an ip helper-address. Key to doing this well is to get the planning correct. Take your time planning it and look for any gotchas. Key things to be aware of 1) do any of the devices in your vlan at present need L2 adjacency ie. they need to be able to broadcast to each other for an application to work. This is rare these days and it can be worked around but something to check. 2) Hardcoded IP addresses. Hopefully you haven got them but it needs checking ie. some device has a hardcoded IP so it knows which server etc. to talk to. Again, rare these days but still needs checking. Having said that if you stick with the current addressing but just split it up most of the IP addresses could stay the same on the devices. The only issues you may get is where the IP address of an existing device suddenly becomes the broadcast address for example of your new smaller subnet. If you make sure when you get these that it is a PC rather than a device with a hardcoded address you should avoid problem 2 above. Jon
