Replace ACSLS host in Netbackup

This is my first post.  Be gentle.  

I have a NBU environment with a master and four media servers.  The equipment is in a datacenter where the library is shared between customers using the data center.  The managers of the DC are replacing the ACSLS Host used by Netbackup.  The new ACSLS host is configured to operate the same, the name and IP are chaning.

What are my options for chaning or replacing the ACSLS host in Netbackup?
