Hi @ryan190 ,
Thank you for reaching us on community!
I would first recommend, migrating VSE policies to ENS by using 'endpoint upgrade assistance'. This would ensure that the same settings in VSE policies are configured for ENS as well . once the policy is migrated, you can assign this to the servers that you wish to upgrade from VSE to ENS.
Also, i would recommend to check the VSE to ENS policy mapping o understand the policy migration :
https://docs.mcafee.com/bundle/endpoint-security-10.5.0-migration-guide-epolicy-orchestrator-windows...
In case if you want to just the current ENS policy to work with "would have blocked" event, you can enable "report " only for all the rules in ENS - > Access protection policy and ENS -> exploit prevention policy . But, do note that this could be a major security risk to change all rules to "allow ".
I hope you find this helpful!
