Server Readdressing project & VLANS
Hi
We have a customer whose servers are on a dedicated VLAN using address range 152.114.x.x/16. They want to migrate these servers to a private address range of 192.168.60.x/24 but dont want to have to do all the servers in one hit.
Is there a way I can either add a secondary IP address to the existing VLAN or create a new VLAN to configure all of the switches and then enable them to migrate the IP's at their own pace?
thanks

Thanks for your reply
How would this work for virtual servers? Customer has about a dozen Citrix Xen Server Hosts each with about 20 virtual servers and they would want to move the VM's one at a time.

Many thanks for this,
I have different configs on some ports for the same VLAN as below (I have included an abstract of some of the config) , how do I ensure that the ports in question are able to process traffic for both my existing server VLAN which is VLAN6 and my new server VLAN which is to be VLAN60? I want to be able to pass traffic on both until the server ip address modifications have been completed.
interface vlan 2

Sorry I also have ports on other switches in Access mode as below
interface range ethernet 1/e1,1/g2,4/g(1-2)
switchport access vlan 6
Should these be changed to General and the new VLAN60 added?
