Agent-based / Agentless data collection CCS

Hi, 

I have to implement a ccs installation and concerning the targeted assets i have the following Types:

-Windows 2000,2003,2008,2008R2

-Solaris 8,9,10,11 UNIX 

-IBM AIX 5,6

-Oracle 9i,10g,11g,12c UNIX

-MSSQL 2005,2008,2008R2 Windows

For the following i am 80% sure that i can collect data AGENTLESS:

-Windows 2003,2008,2008R2

-Solaris 9,10,11 UNIX 

-Oracle 9i,10g,11g,12c UNIX

-MSSQL 2005,2008,2008R2 Windows

But for the rest i can't find anything documented:

-Windows 2000

-Solaris 8

-IBM AIX 6 (this one i believe that works WITH Agent)

I was adviced by this URL:

Can anyone help me?
