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

Thnx

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?
