I am having two mailbox exchange 2007 sp2 servers on windows server 2008 sp2 in single copy cluster. I am introducing a new subnet in my datacenter and planning to migrate those servers to the new subnet . Any one can help in step by step procedures to do this ? Is this supported ?.ammarhasayen

Hi, Have a look into this article for cluster IP change: http://blogs.technet.com/b/dblanch/archive/2009/04/10/changing-the-ip-address-of-an-exchange-cluster.aspx & to change the IP on Exchange Virtual Server http://technet.microsoft.com/en-us/library/aa997813(EXCHG.65).aspxRipu Daman Mina | MCSE 2003 & MCSA Messaging

It should be no trouble. It's really a Windows Clustering thing, not an Exchange thing. Exchange really doesn't have any trouble with IP address changes.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
