Rules mismatch - migration from 5.3 to 10.1

Hello guys,

i am having queries regarding the RULES in 5.3 and 10.1

while migration from 5.3 to 10.1, All the funcs, risks, mitigations etc are exactly copied in 10.1. But After generating the rules, there is a mismatch in the 5.3 rules count and 10.1 rules count. I activated  BC sets but while migrating from 5.3 selected the option overwrite. So i think only 5.3 rules get updated in the system. Not able to understand why the mismatch of rules came.

Secondly how can i see the rules count in 5.3 and 10.1 as of now i am checking in report RULE LIBRARY in 5.3 and 10.1. Is there any way to download the rules based on system like DEV , QA in 5.3 and 10.1?

I have seen one note 1713294 which deals with logic change in rules creation and will not get the same rules as in 5.3.

Regards,

Ravi.
