cPanel Backup Restored on CyberPanel

I have restored my full cPanel backup via CyberPanel Python script successfully on my VPS (CentOS 7 +LAMP+CyberPanel). I need to know:

  1. Unnecessary files and folder/dir of cPanel?
  2. How to locate them?
  3. How to delete them?
    I am asking that because on my VPS, cPanel restored can take much more spaces than actual website contents and databases as well it is creating problems with DNS-Records.
    For some domains, it shows the previous (hostgator) DNS-Records.
    I need to locate & delete all that unnecessary files/folders of my cPanel backups at my new VPS.
