Change of DC IP Address - What issues will arise?

Hi,

We will be changing the IP address/host name of current DC, if the DC holds some FSMO roles will doing this cause any problems? We will be changing the IP address/host name so it should be about a minute switch over. Will this cause any problems if the DC holds any FSMO roles or services? Do any commands need to be run after doing this?

We have other DC's in the Domain.
