Backward compatibility with SCSP 5.2.0 policies?

Hi,

I'm trying to import detection policies from SCSP version 5.2.0 into DCS 6.0. But i am getting errors each time. I have imported many policies in the past so i know how it is done but this is just not working.

So I'm wandering is there a compatibility issue with importing polcies into 6.0 that were made in the 5.2.0 version?

Also will the compatiblity issue extend to 6.0 agents not working with 5.2.0 agents?
