Hi Erdem,
From a support engineer perspective, we have had several customers that have implemented CA SAF HFS Security.
Some of their comments related to ..
1) the conversion utility requires work before implementing any permissions.
2) the complexity depends on the size of your HFS environment - number of rules that need to be written.
3) with CA SAF HFS Security active, there is no FSACCESS validation when accessing files.
If you have any specific questions, please do not hesitate to open a case with support.
regards
Ross
