Bulk Case creation scheduled job was completely disabled in Rome and has been replaced by Create bulk HR cases script action which is triggered by sn_hr_core.process_bulk_case_request event. The script runs asynchronously and you don’t have to worry about setting up the right time for the job

Employee Relation COE (sn_hr_core_case_relations) is no longer available, instead new customers are going to use sn_hr_er_case table which is sets in Human Resources Scoped App: Employee Relations [com.sn_hr_employee_relations] not in Human Resources: Core App. New Employee Relation provides a data model that supports tighter security and saves tons of work that usually spends on customization ACL or data segregations
