Change Amanda Client

[hpl]

Hi,
I am running amanda-2.3.0.4. Does anyone who knows how to 
change amanda clients. Such as delete an existing client and
add another new client.
Backup server is Solaris 2.6 (Ultra 60),
the client needs to be removed is Solaris 2.6(Ultra 30) and
the client needs to be added is Solaris 2.8(Ultra 80).
Thanks
