You must have a boot server for each type of client that you want to protect. For example, a Solaris client requires a Solaris boot server, a Windows client requires a Windows boot server, and so on.

For UNIX, Linux, and legacy Windows restores, a boot server at a particular operating system version can only host SRTs of the same operating system version or lower. For example, a Solaris 9 boot server can host Solaris 8 and Solaris 9 SRTs, but not Solaris 10 SRTs.

For UNIX, Linux, and legacy Windows restores, a client at a particular operating system version requires an SRT of the same operating system version.
