Upgrade from Netbackup 6.5.6 to 7.5

Hi all experts ,

I want to Upgrade my  Master Server & Client as well as admin console to version 7.5 . I am in Solaris 10 Sparc 64 bits. I have downloaded the following files through file connect

NetBackup_7.5_Solaris_Sparc64.tar.gz

Netbackup_7.5_CLIENTS_tar-gz.1of3

Netbackup_7.5_CLIENTS_tar-gz.2of3

Netbackup_7.5_CLIENTS_tar-gz.3of3

My questions is

1) Where i could down load the admin console 7.5?

2) Can i upgrade my server and clients from 6.5.6 to 7.5 directly. I read the upgrade guide and it says that 7.5 is compatible with 6.5

Please let me know.
