Swapping DCs IP addresses

Posted on 2006-04-26

In our Windows 2003 network, we have 3 DC/GCs and about 20 member servers including Exchange servers.
We want to improve the performance by replacing two GCs with more powerful servers, then we want to demote these 2 old GCs.  

I am thinking about installing the new GCs and then swap their IP addresses with the ones that is being used by current GCs therefore I won't need to change DNS server address settings on all 20 member servers.  Is this safe to do? I am wondering whether it will makes a problem with Exchange and AD replication.

    Hi juragan,

    whenever you change an IP on a DC you are best off creating fresh records in DNS anyway

    promote your new ones, take over the roles, demote your old ones and change the IP and create new records

    thats my opinion anywayz
