Hi Vlad,
Security Group data is in each module such in AP this would include APSCGR'1, APSCGR'2, APSCGR'R with data extensions.
Receivables are ARSCGR'1 etc.
Backup or rename the security groups that you want update, and copy in the files of the security groups that you intend to update for each module.
Before copying in the files, make sure that your versions of software modules are the same.
Best,
Brian
