Best Order - Changing IPs addresses on DC/DNS servers

I am really wanting input on the best logical steps to take in the following scenario.

I have a domain controller I want to retire.
I have a new domain controller active.
I need the IP of the older DC to become that of the newer.  The name of the server DOES NOT need to change.
This because the IP address is used throughout the domain, particularly as a primary or secondary DNS reference, and as an LDAP reference.
DNS and LDAP are installed on both, neither is a GC server.

Would the following order make the best sense?  Is there something I might be missing?

1.      Change the IP of the old. (and let that propagate)
2.      Change the IP of the new. (to that previously of the old)
3.      Demote the old DC.

Your steps are fine just make sure the change propagates all the way around.   How big is your environment?

Also definitely do this after hours/weekend to minimize any potential impact to the users.

Thanks

We have 5 sites.  3 of them have 2 DC/DNS servers, one has just 1, and the primary site currently has 3 DC/DNS servers.  We are at a Windows 2008 R2 level and most of the DCs are now Windows 2012/R2.  I am in the process of swapping out the 2008 R2 servers.

ok, then it won't take you long to check and verify the DNS records and it won't take long for the changes to happen.

Thanks
