Altiris Infrastructure Monitoring

Hello all,

Back in the 6.x days, I believe that Monitor Solution was free until you purchased an actual monitor pack, unless it was the Altiris Infrastructure Pack. 

I know that 6.x is fully EOL, but is this still the same situation?

Also, is Monitor Solution 7.1, 7.5 & 7.6 free until you use a monitor pack, and if so, if one uses the Altiris Infractrusture Pack for these versions, does the product still remain free? 

Would it be possible to utilise 7.x agentless monitoring to monitor a 6.x infrastructure?

Thanks in adavnce, SK.
