Nope, there's plenty of documentation on cisco.com around changing the hostname and/or IP of the UC products, make sure to thoroughly read and understand the exact order of the procedure to avoid issues, read the documentation for your release.
EDIT: not to mention that DRS requires the SAME IP to be used, so, if you do that, you would not even be able to restore your configuration due to the IP mismatch between the backup and the new server.
