Windows Agents on servers that had a domain change

We HAD two domains until recently, the Backup Exec servers sits in "domain A", along with several servers that have Windows Agents.  In "domain b" are other servers that have Windows Agents installed.  We have done away with "domain b" and have moved those servers into "domain a".  In the BUE2014 console, under Backup and Restore, I see the servers that were moved still listed as "server.domainb".  Is there a way without an agent removal and reinstall to get those servers to be recognized as being in their new domain?  The server names and IP addresses haven't changed, just their domain membership.  Thanks!
