TSM CLient TCp/IP Chnage

Hi,
We have few windows & UNiX servers, where there names have been changed.
As the Infra team have changed the naming convention for the servers. As i am aware that after changing the server name when we
Q Se from client its TCP/IP name will be updated in the node of TSM server.
But if the TCP/IP name or IP has changed do i have to make any changes to have backup.
as Bckup is failing now.
